1. 2013 BMW Z4 sDrive35i
The 2013 BMW Z4 sDrive35i is a luxury roadster that combines performance, technology, and the joy of open-air driving. It features a turbocharged 3.0-liter inline-six engine producing 300 horsepower and 300 lb-ft of torque, allowing the sDrive35i to accelerate from 0-60 mph in around five seconds.
The higher-performance sDrive35is achieves the same sprint in 4.4 seconds. Transmission options include a 6-speed automatic or 8-speed manual, while the sDrive35is comes with a seven-speed dual-clutch automatic for rapid shifts. Prices for a used 2013 Z4 sDrive35i range from $18,978 to $20,201.
The Z4 uses a front-engine, rear-wheel-drive layout that provides nearly 50-50 weight distribution and neutral handling. Electronic power steering, rear-brake-assisted stability, and a low center of gravity contribute to precise cornering. The Overboost system in the turbo engine delivers short bursts of extra torque for strong acceleration.
While the Z4 does not have a traditional limited-slip differential, it is both stable and engaging in spirited driving. Driving Experience modes adjust throttle response and gearbox behavior, though differences between Comfort, Sport, and Sport+ are subtle.
The Z4 features a power-retractable hardtop that stows in about 20 seconds, reducing trunk space to room for only small luggage. The cabin is technology-heavy yet driver-focused, offering a mix of luxury and usability. With the top down, the Z4 provides a classic roadster experience with wind, engine sound, and a strong connection to the road.
Standard technology includes iDrive infotainment, premium audio, USB and iPod connectivity, Bluetooth, and keyless entry.

The sDrive35is uses a dual-clutch transmission to deliver power quickly and smoothly while allowing the driver to focus on handling and driving enjoyment.
The 2013 BMW Z4 sDrive35i is a refined and powerful roadster suitable for open-air driving enthusiasts. It balances performance, luxury, and technology, making it a strong option for those looking for a used roadster under $20,000. Buyers who prioritize a purist driving experience or superior handling may prefer the Porsche Boxster S, but the Z4 remains a compelling choice for spirited driving.
2. 2010 Audi TTS
The 2010 Audi TTS is a high-performance version of the standard TT, offering German build quality and sporty driving dynamics at a price well below Porsche alternatives. Powered by a turbocharged 2.0-liter four-cylinder engine, the TTS delivers 265 horsepower and 258 lb-ft of torque.
Mated to a six-speed dual-clutch automatic transmission and Audi’s Quattro all-wheel-drive system, it accelerates from 0-60 mph in 4.8 seconds, making it competitive with rear-wheel-drive sports cars like the BMW Z4 and Porsche Cayman S. Used prices range from $15,222 for the coupe to $15,867 for the convertible.
The TTS balances straight-line speed with cornering capability. The all-wheel-drive system compensates for its slightly higher weight, helping the car maintain traction during spirited driving. Adaptive damping and a 10-millimeter lower ride height keep cornering attitudes flat, while Continental ContiSportContact 3 tires provide excellent grip, reaching up to 0.95 g.
Braking performance is strong, stopping from 70 mph in just 154 feet. The steering is light at low speeds but becomes more responsive at higher speeds, and the car displays mild understeer typical of front-biased all-wheel-drive setups. Stability control can be turned off, though the system engages late and is rarely intrusive.
The second-generation TTS adopts styling cues from the Audi R8, including sharp headlights, a low roofline, and a rear spoiler, giving it the appearance of a scaled-down supercar. Interior quality is high, with a driver-focused cockpit and tactile controls. Rear seats are small, making it best suited for two occupants. Ride quality is firm, especially with the optional 19-inch wheels, which can feel harsh over rough roads.
Standard TTS technology includes a six-speed DSG transmission, adaptive damping, and Quattro all-wheel drive. Optional packages, such as the $5000 Prestige package, add navigation, upgraded audio, and other convenience features.
The 2010 Audi TTS offers excellent acceleration, precise handling, and refined design at a price significantly lower than the Porsche Cayman S. While it exhibits minor turbo lag and a firm ride, the TTS remains a compelling choice for enthusiasts seeking a capable and stylish German sports coupe or convertible.

8. 2008 BMW 135i
The 2008 BMW 135i delivers a compact and powerful alternative to the larger 3 Series, fitting the same twin-turbocharged 3.0-liter inline-six from the 335i into a smaller, lighter package. Generating 300 horsepower and 300 lb-ft of torque, the 135i accelerates from 0-60 mph in just 4.7 seconds.
Buyers can choose between a 6-speed manual or a 6-speed automatic transmission. On the used market, prices range from $8,103 to $16,041, making it an appealing entry point into BMW’s sporty coupe lineup.
Despite its smaller dimensions, the 135i weighs 3,373 pounds, which affects its agility compared to the classic 2002 coupe. Acceleration is immediate and thrilling, with the turbocharged engine delivering strong torque throughout the rev range.
Grip is abundant, but steering feels heavy, and the manual transmission suffers from a rubbery clutch and imprecise engagement. The six-speed automatic is less refined than the 335i’s ZF unit. The car excels in straight-line performance but does not provide the nimble handling that some enthusiasts might expect from a compact BMW coupe.
Inside, the 135i uses materials and design similar to the 3 Series, including a driver-focused center stack. Front seats are supportive but may require optional upgrades for enhanced comfort. Rear seating is extremely limited, suitable only for small items or children, and trunk space is minimal, reducing practicality for everyday use.
The 135i departs from the charm of the classic 2002, featuring a high beltline and compact greenhouse that restricts visibility. Its styling combines contemporary BMW elements with unusual proportions, resulting in a look that many find less appealing than the car it was intended to echo. Certain details, like the curve of the rear pillar, are attractive, but the car’s design is often regarded as awkward.
The 2008 BMW 135i stands out as a fast, engine-focused compact coupe with thrilling straight-line performance. However, its weight, heavy steering, and cramped interior limit its agility and practicality. Enthusiasts seeking a modern successor to the 2002 will find the 135i exciting but flawed, offering power and driving excitement at the expense of finesse and everyday usability.
9. 1992 Mitsubishi 3000GT VR4

Powered by a twin-turbo 3.0-liter V6 producing 300 horsepower and 307 lb-ft of torque, the VR4 could reach 60 mph in just 4.8 seconds.
Its five-speed manual transmission and rally-derived all-wheel-drive system gave the car excellent traction and handling, making it a formidable performer on both highways and winding roads.
The 3000GT VR4 stood out in the early 1990s due to features uncommon in production cars at the time. Electronically Controlled Suspension allowed drivers to switch between sport and tour modes, while the Active Aero system automatically adjusted the front spoiler and rear wing to optimize downforce.
Four-wheel steering improved low-speed agility and high-speed stability, helping offset the car’s relatively heavy weight. Despite its technological complexity, the VR4 remained thrilling to drive, delivering strong acceleration with minimal turbo lag and impressive grip around corners.
The interior was luxurious for its time, with leather seats, automatic climate control, and a driver-focused cockpit. Pop-up headlights added to the car’s distinctive styling, and the exhaust note remains a highlight for enthusiasts, especially when modified. The aerodynamic design continues to turn heads decades later.
Potential buyers should be aware of some challenges. The complex electronics, Active Aero components, and suspension systems can fail and are costly to repair. Age-related issues with seals and wiring are common, and replacement parts can be difficult to source. The low roofline limits headroom, and the car’s weight slightly affects agility compared with lighter Japanese sports cars.
The 1992 Mitsubishi 3000GT VR4 delivers a high-tech, high-performance driving experience with a combination of twin-turbo power, all-wheel drive, and active aerodynamics. It rewards enthusiasts who value innovation, distinctive styling, and strong performance, though ownership requires a commitment to maintaining its sophisticated systems. The VR4 remains a powerful and unique Japanese sports car from the early 1990s.
The nine sports cars highlighted in this list demonstrate that high-performance driving does not have to come with a Porsche price. Models like the 2005 Mercedes-Benz SLK 55 AMG and 2008 BMW 135i offer turbocharged or V8 power, agile chassis, and luxury appointments that make every twist of the road exciting.
The Chrysler Crossfire SRT-6 blends American and European engineering, while the Mitsubishi 3000GT VR4 remains a technological marvel with all-wheel drive, active aerodynamics, and twin-turbo performance.
Each car brings a distinct experience, whether it is the Corvette’s raw American muscle, the Z4’s refined open-top roadster thrills, or the Audi TTS’s precise all-wheel-drive cornering. These vehicles prove that enthusiasts can enjoy sharp handling, engaging acceleration, and the visceral sensation of driving without paying six figures for a European supercar.
For budget-conscious buyers, this list provides a range of compelling options that balance affordability with excitement. Owners can experience spirited driving, weekend track sessions, or daily thrills while maintaining access to parts, service, and community support.
These nine sports cars offer the chance to “hunt down a Porsche 718” in performance and enjoyment, making the dream of high-performance driving attainable for those willing to explore beyond the conventional luxury market.
