Choosing a used Audi that costs under $20,000 can be a satisfying experience for anyone who appreciates engineering, design, and driving engagement. For many buyers, this price range offers a chance to own something special without paying new car prices.
Audis have long been known for their combination of performance and comfort, and even older models retain much of the charm and capability that made them famous in the first place. The trick is knowing which versions of these vehicles have the balance of reliability, features, and style that make them worth considering.
As cars age and accumulate mileage, certain models gain reputations for being more dependable than others. Some are known for robust engines and transmissions that stand the test of time, while others offer a blend of practicality and performance that still feels exciting to drive.
A used Audi can be an affordable entry into premium car ownership, but it also requires knowledge about typical issues, maintenance needs, and the kinds of modifications that owners might have made over the years. Research and inspection become vital parts of the process, and buyers who take time to understand what they are getting will often find themselves rewarded.
In this article, we will look at ten Audi models you can often find for under twenty thousand dollars. These options range from compact sporty coupes to larger sedans and versatile crossovers.
Each entry will explain why that model remains appealing, what strengths it brings to the table, and what you might want to keep in mind when considering one. This guide aims to offer a balanced view that helps you focus on real-world ownership experience, usability, and enjoyment rather than just a list of names.
Whether you are interested in a fun weekend car or a daily driver with some premium touches, the list ahead covers a broad range of Audis worth considering. Let’s begin with a classic choice that often stands out in used car listings and proves that you do not always need to spend top dollar to find something that feels special and capable.
1. Audi A4 (B7 Generation)
The Audi A4 B7 generation is one of the most common Audis found under twenty thousand dollars because so many were made. This era delivered a good mix of technology and mechanical simplicity that appeals to drivers who want classic German character.
With four-cylinder and V6 options, there is a version for fuel efficiency or stronger acceleration without too much fuss. Many of these cars also came with the quattro all-wheel-drive system that helps grip on wet or slippery roads.
One big reason the B7 remains tempting is its balance of chassis dynamics and comfort. It is composed enough in corners to inspire confidence despite its age, yet compliant enough for daily driving. The interior was high quality for its time and still feels more upscale than many cars in this price range. Leather seats, dual-zone climate control, and straightforward infotainment may be dated but remain functional and solidly built.
Maintenance history matters with the B7 because some common issues include oil consumption and timing belt service requirements. Buyers who find records showing regular care typically fare much better in ownership costs. Replacing suspension components at higher mileage can also rejuvenate the driving feel and reduce clunks that sometimes develop over years of use. A careful pre-purchase inspection goes a long way with this generation.
For someone seeking a classic compact luxury sedan that feels engaging and capable, the Audi A4 B7 often checks many boxes. When priced right and in good condition, it can be a rewarding choice that punches above its price tag. Enthusiasts often modify these cars as well, so well-sorted examples with performance upgrades sometimes appear on the market.
2. Audi A4 (B8 Generation)
Upgrading from the B7, the Audi A4 B8 generation brought refined styling and updated engineering that still feels relatively modern today. Many buyers appreciate the sleeker exterior and more spacious cabin compared with earlier versions.
The B8 also benefited from improved interior materials and better noise insulation, which helps the car feel less dated even as mileage rises. It is easy to see why this generation remains popular among budget-conscious Audi buyers.
Performance in the B8 depends on the engine and trim, with turbocharged four-cylinder units becoming more common. These powerplants offer a good mix of efficiency and usable torque, giving the A4 enough energy for highway passing and everyday tasks. Quattro remains available on many trims, ensuring confident traction in varied weather conditions. The transmission choices typically include smooth-shifting automatics that complement the driving experience.
Some B8 models may come with optional features like navigation, heated seats, and premium audio systems, making them feel well-appointed for the money. However, like any used premium car, options can vary widely by individual vehicle.
Prospective owners should evaluate the specific configuration and service records to ensure nothing critical has been neglected. A well-maintained B8 A4 can deliver years of service if treated with care.
Repair costs for used Audis can be higher than non-luxury brands, but the B8’s reliability ratings are generally respectable compared with other Audis of similar age. Once again, a thorough inspection is recommended to uncover any lingering issues before purchase. When you find a B8 A4 that ticks the right boxes, it can be one of the most rewarding Audi choices under twenty thousand dollars.
3. Audi A6 (C6 Generation)
The Audi A6 C6 generation represents the brand’s larger family sedan offering that often slips into the used price bracket under twenty thousand. Buyers attracted to this model usually appreciate space and presence because the A6 sits above the A4 in size and refinement. It delivers a comfortable ride suited to longer trips and family duties without sacrificing the premium feel expected of an Audi. The interior often feels roomy, with supportive seats and thoughtful design touches.
Under the hood, the C6 offered a range of engines from dependable V6 units to more powerful configurations that make freeway merging effortless. Many of these vehicles came with quattro all-wheel-drive, giving them an edge in traction over competitors with two-wheel drive. Steering and suspension work together to give the A6 C6 a composed demeanor in many driving situations, making it capable if not sporty.
Because the A6 is larger and more complex than an A4, prospective owners should be mindful of maintenance and repair history. Timing chain issues on certain engines and electronic gremlins can crop up, so vehicles with documented service records tend to be more desirable. Suspension components may also need attention as mileage rises, but these services can often bring new life to an older sedan.
When cared for correctly, the C6 A6 rewards owners with a premium experience that still feels substantial relative to the price. Comfortable seating, a balanced ride, and generous interior space make it a compelling choice for anyone seeking a high-end feel in a used car. For those who want larger proportions and highway comfort, this model remains tempting.
4. Audi TT (Mk1)
The first generation of the Audi TT stands out for its distinctive styling and fun personality. Even as older used cars, these two-door coupes often catch attention with their rounded lines and sporty proportions. The interior follows a similar design philosophy, with aircraft-inspired gauges and a driver-focused layout. For buyers who value styling alongside performance, the Mk1 TT offers a unique package that feels more special than many competitors.
Driving a Mk1 TT can be engaging because it is light relative to other Audis of its era and often comes with all-wheel-drive. Turbocharged four-cylinder engines give strong mid-range torque that makes the car feel lively for everyday driving and weekend blasting. Manual transmissions are available in many examples, and these often appeal to enthusiasts looking for more connected control.
Owners should be aware that specifics vary depending on how previous drivers treated the car. As with other older performance-oriented vehicles, maintenance records can mean the difference between a gem and a headache. Common issues like differential noise or turbocharger wear should be checked before purchase. A clean history and thorough inspection help prospective buyers make a confident choice.
Once properly vetted, the Mk1 Audi TT offers a blend of style, performance, and personality that remains rare at this price point. Its combination of sharp looks, engaging driving dynamics, and Audi engineering makes it compelling for those seeking an affordable sports coupe. For many owners, the fun factor alone makes it worth consideration.
5. Audi A3 (8P Generation)
The Audi A3 8P generation is a compact model that still delivers premium touches often missing at this price. It is smaller than the A4 or A6, which helps it feel nimble in urban environments and efficient in daily use.
The interior remains well assembled, with supportive seating and quality materials that make the car feel upscale compared with non-luxury hatchbacks and sedans. This combination attracts buyers who want premium feel without paying luxury prices.
Performance options vary, but many A3s feature turbocharged four-cylinder engines that balance decent power and reasonable fuel economy. Quattro is available on a number of trims, giving confidence in wet conditions and corners. The driving experience of an A3 feels lighter and more agile when compared with its larger Audi siblings. It remains enjoyable for both city commuting and longer drives.
As with other used cars, checking service history is crucial because the A3’s reliability depends on how it was treated. Older engines may have issues with high-pressure fuel pumps or other components if neglected, so thorough evaluation before purchase is important. Suspension wear in cars with many miles may also be noticeable, but replacement parts are widely available.
For buyers seeking a premium compact with a direct feel and solid engineering at a lower price, the Audi A3 8P often fits the bill. Its balance of refinement and liveliness makes it attractive for those who want a smaller car that still feels special. With careful selection, it can provide years of enjoyable use.
6. Audi A5 (First Generation)
The first-generation Audi A5 brings coupe styling and a presence that feels luxurious even when older. Its long roofline and clean proportions continue to turn heads on the road. Inside, the cabin often features attractive design and materials that feel more upscale than many cars in the same price bracket. Buyers who prioritize style often find the A5 rewarding.
Driving dynamics are a strong point for the A5 because it often balances comfort and agility well. Available quattro all-wheel-drive helps the car feel composed in corners and confident in wet weather. Engine options range from efficient four-cylinders to stronger V6 units, giving prospective buyers flexibility in prioritizing fuel economy or power. The steering feels precise enough to make everyday driving engaging.
Used A5s can have varied maintenance histories, so prospective owners should carefully review service records and inspect critical components. Suspension wear, brake condition, and electronic modules can need attention if unsupported over time. However, a well-maintained example can be reliable and pleasant to live with for the long haul. Timing belt replacement and regular oil changes are essential for longevity.
The A5 also appeals because of its resale value and timeless looks. Even older models retain a sophisticated presence on the road. Optional packages such as S line trims enhance appearance and add sportier suspension tuning. Interior ergonomics remain thoughtful, with controls logically placed and infotainment that, while dated, still functions well.
7. Audi Q5 (First Generation)
For buyers looking at crossovers rather than sedans, the first-generation Audi Q5 represents a compelling used choice. It sits in a sweet spot because it offers the utility of an SUV with Audi’s premium traits. With quattro all-wheel-drive standard on many trims, it gives confident traction and a composed feel on varied surfaces. Interior volume and cargo space make it practical for families.
Driving the Q5 feels stable and refined because suspension tuning softens bumps without feeling floaty. Steering is communicative enough to make highway driving pleasant and expressive. Engine options typically involve turbocharged four-cylinder units that provide a good balance of power and fuel economy. Many owners appreciate the smooth transmission that partners well with these engines.
Older Q5s should be looked at with service history in hand because timing chain tensioners and oil consumption have been noted on some examples. Ensuring regular maintenance and addressing any pending repairs before purchase helps avoid surprises. Suspension components and electronics that control comfort settings should also be checked. The brakes and wheel bearings should be inspected for wear as mileage climbs.
The interior also remains a strong selling point, with comfortable seating and quality materials that feel premium for the price. Storage compartments are well thought out, and the rear seats fold flat for cargo versatility. Optional technology like navigation and parking sensors makes driving easier and more enjoyable. The combination of utility and refinement explains its continued popularity in the used market.
8. Audi Allroad (C5 and C6)
The Audi Allroad variants based on the A4 and A6 platforms offer rugged looks and extra practicality. These wagons bring more cargo space and slightly higher ride height than their sedan counterparts. Quattro all-wheel-drive remains a key feature that gives these cars traction and confidence in wet or slippery conditions. For buyers who appreciate versatility, the Allroad stands out.
The suspension setup in Allroad models adapts well to varying surfaces because it was designed with light off-pavement use in mind. Many examples include adaptive damping that smooths bumps efficiently. The interior is similar to the A4 or A6 from which it descends, meaning quality materials and solid ergonomics are part of the package. Practical touches like fold-flat seats add daily utility.
As these wagons tend to be older and possibly high mileage, inspection is important. Air suspension systems on some versions require particular attention because repairs can be costly when neglected. Engine reliability and drivetrain condition should be verified with a thorough service check. Electrical components and interior comfort features should also be confirmed to be operational.
Another appealing aspect of the Allroad is its long-distance comfort. Even fully loaded with passengers or cargo, it maintains stability and composure on highways. Visibility is good, and the cabin noise remains reasonable for a vehicle with this type of suspension. Owners who want a unique blend of wagon practicality and Audi refinement often consider this model a standout choice.
9. Audi S4 (B5 Generation)
The Audi S4 from the B5 generation gives enthusiasts access to a performance sedan at an affordable price. With a loud and powerful V6 engine, it delivers acceleration and personality that many other cars in this price range lack. Quattro all-wheel-drive and sport-tuned suspension help keep power on the pavement and make handling more engaging than typical sedans. The S4 combines sportiness and everyday usability.
Interior appointments in the S4 often include sport seats, premium materials, and upgrades like Bose audio or heated leather. The combination of performance hardware and thoughtful creature comforts makes it feel special to drive and live with. Many enthusiasts appreciate the way the S4 feels balanced in corners and lively on straights. Its classic Audi design continues to appeal to collectors.
Because this is a performance model, previous owners may have pushed the car harder than normal. Prospective buyers should check for modifications, clutch wear, and service records showing regular maintenance. Some common S4-specific issues include cooling system wear and suspension bushings that may fatigue over time. Timing belt replacement and attention to the driveshafts can ensure long-term reliability.
For buyers who enjoy spirited driving without stepping into exotic car territory, the S4 is often unmatched at this price. It offers a rare combination of engine note, handling, and all-weather traction. Well-maintained examples can be surprisingly comfortable for daily driving while still providing excitement on weekends. This model is a favorite among enthusiasts seeking value and performance.
10. Audi A8 (D3 Generation)
The Audi A8 from the D3 generation represents the brand’s flagship sedan that sometimes falls under twenty thousand dollars due to age and mileage. This full-size luxury sedan offers features often found in much more expensive vehicles, such as advanced electronics, premium leather, and generous rear legroom. For buyers who want the most comfort and presence for the money, the A8 stands out.
Engine options include robust V8s that deliver effortless acceleration and smooth freeway cruising. The ride quality feels composed and refined, which helps distances feel shorter and highways feel relaxed. Audi’s quattro all-wheel-drive is available on many trims, contributing to sure-footed traction when conditions demand it. The cabin places passengers in a world of comfort that belies its age.
Older large sedans require careful evaluation because complex electronics and air suspension systems can need attention. A thorough inspection is essential to confirm that these premium features still function as intended. Cooling systems, brakes, and transmission history should all be part of a pre-purchase review. Regular fluid changes are critical to keep the drivetrain and hydraulic systems healthy.
The A8 also impresses with space and amenities that rival newer vehicles. Rear passengers benefit from legroom, adjustable seating, and climate controls. Sound insulation reduces road noise, making long drives effortless. For buyers who prioritize comfort and want a full-size sedan that feels special, the D3 Audi A8 remains a rare and desirable option in the under twenty thousand dollar range.
