Buying a used car at the right time can make a meaningful difference, and iSeeCars’ latest research suggests that the end of the year is one of the strongest periods for finding a genuine bargain.
Its analysis found that New Year’s Eve and New Year’s Day produce 58.6% more good used-car deals than an average day, making the two days the second-best time of the year to shop. Only Martin Luther King Jr. Day performs better, with 65.5% more deals than average.
The study analyzed more than 40 million used-car sales from 2024 through October 2025. iSeeCars defines a good deal as a vehicle listed at least 10% below its estimated fair-market value. Across the entire market, the average chance of finding such a deal on a given day was 13.7%.
That distinction is important. The 58.6% figure does not mean used cars are 58.6% cheaper on New Year’s Eve. It means shoppers have a substantially higher probability of encountering vehicles that meet iSeeCars’ definition of a good deal. For buyers who can wait, that makes the final days of December particularly interesting.
Why New Year’s Eve Can Be Such a Strong Buying Opportunity
The timing is not accidental. Used-car dealerships have financial reasons to keep inventory moving as the calendar year closes. Every vehicle sitting on a lot represents money tied up in inventory, while dealers also have monthly, quarterly, and annual sales objectives to consider.
That pressure can create opportunities for shoppers who arrive prepared. iSeeCars’ research shows that the strongest periods are concentrated in the colder months.
After MLK Day, New Year’s Eve and New Year’s Day rank second, followed by January with 55.6% more good deals than an average day. Presidents’ Day ranks fourth at 47%, while February produces 36.2% more deals.
The pattern is striking because it suggests that the best opportunities are not necessarily associated with the major summer sales events that receive the most advertising.
In fact, iSeeCars found June to be the worst month for used-car deals, with 22.8% fewer good deals than average. July 4th was similarly weak, producing 22.4% fewer deals. May and July also ranked near the bottom.
That gives New Year’s Eve an advantage beyond the holiday itself. It falls inside a broader period when used-car deals are more plentiful.
Temperature may even play a role in this seasonal pattern. iSeeCars says used-car prices tend to follow average temperatures, with both falling between November and March and reaching their lowest point between December 31 and February 28.
There is also a practical reason dealers may become more flexible at the end of the year. A vehicle that has remained unsold for several weeks can become increasingly expensive to carry. Dealers may prefer accepting a smaller margin rather than entering another year with aging inventory.
That does not mean every dealer will automatically slash prices on December 31. Popular vehicles with limited inventory can remain expensive because demand is strong. But when several comparable vehicles are available, the buyer has more leverage.
This is where research becomes essential. A shopper should know the typical market price before entering negotiations.
If similar vehicles are selling for $25,000 and one dealer advertises a particular example for $22,000, the buyer can determine whether the price is genuinely competitive. Without that research, a supposed holiday promotion may sound better than it actually is.
iSeeCars’ methodology helps put the statistic into perspective. The company calculates the percentage of vehicles qualifying as good deals at different times and compares that probability with the average 13.7% chance on a normal day.
So a 58.6% increase represents more opportunities, not a guaranteed discount on every vehicle.
The Best Strategy Is to Combine Timing With Research
New Year’s Eve can improve a buyer’s odds, but the date alone does not make a used car a good purchase.
Condition, mileage, accident history, maintenance records, and vehicle-specific reliability still matter. A heavily discounted car with major mechanical problems can become more expensive than a properly maintained vehicle purchased at a higher price.
The same applies to financing. A dealer may reduce the selling price but make up some of that difference through a high interest rate, extended loan term or additional products added to the transaction. Buyers should compare the total amount paid rather than focusing only on the monthly payment.
Shopping early also helps. Instead of beginning the search on December 31, a buyer can identify several suitable vehicles weeks in advance and track their prices. If one remains unsold as the year approaches, the buyer has evidence that can strengthen negotiations.
This strategy is especially useful because iSeeCars has found that not every vehicle benefits equally from year-end pricing.
Its research into December deals has previously shown that some vehicle categories and models are much more likely to receive discounts than others. Popular models can remain expensive because strong demand means dealers have little reason to reduce prices substantially.
That means shoppers should avoid becoming emotionally attached to one specific vehicle. Having multiple options is valuable. If one dealer refuses to negotiate, another vehicle with similar specifications may offer a better opportunity. The more alternatives a buyer has, the less dependent they are on a single seller.
The timing also matters because the end of December is followed immediately by January, which iSeeCars identifies as the best month of the year for used-car deals, with 55.6% more good deals than average. February ranks second among months at 36.2%.
So a buyer who misses a New Year’s Eve opportunity does not necessarily need to rush into a purchase. January can provide another strong window.
There is another useful point in the data: the best holiday is not necessarily the one most people associate with car sales. MLK Day ranks first, while New Year’s Eve and New Year’s Day rank second. Presidents’ Day follows closely behind. Meanwhile, Memorial Day, Father’s Day and July 4th perform considerably worse in iSeeCars’ analysis.
That challenges the common assumption that every major shopping holiday automatically produces the best automotive discounts.
For buyers, the bigger lesson is to look at actual market data rather than relying on advertising.
The current iSeeCars research provides a particularly strong reason to pay attention to the year-end period. The company analyzed more than 40 million used-car sales, and its definition of a good deal requires a vehicle to be priced at least 10% below its estimated fair-market value.
That makes the 58.6% increase in good-deal opportunities meaningful, even though it should not be confused with a 58.6% reduction in vehicle prices.
A well-prepared buyer can use the period to their advantage by researching market values, comparing multiple vehicles, checking vehicle histories and inspecting any car before purchase. If a dealer also has an incentive to clear inventory before the year ends, the combination can create a favorable negotiating situation.
New Year’s Eve is therefore not a magical day when every used car suddenly becomes cheap. It is better understood as a statistically favorable shopping window.
According to iSeeCars, the average day provides a 13.7% chance of finding a good used-car deal, while New Year’s Eve and New Year’s Day offer 58.6% more opportunities than that average. MLK Day is even stronger at 65.5%.
For someone who needs a car immediately, waiting until December 31 may not make sense. But for a buyer who has flexibility, the evidence suggests that patience can pay off.
The strongest approach is simple: research the vehicle before the holiday, monitor comparable listings, know the fair-market price, and be prepared to walk away. If the right car is still sitting on the lot when New Year’s Eve arrives, the buyer may have more negotiating leverage than at many other points in the year.
The date does not guarantee a bargain. But according to iSeeCars, it significantly improves the odds of finding one.
