Average of each month's gap between the BLS used cars and trucks price index and the same index with seasonal swings removed. 2020 and 2021 are left out: the chip shortage pushed prices up all year and swamped the usual pattern.
The same pattern, year after year
Each row is one year. Blue months were cheaper than that year's average, red months dearer. Summer is red almost every year, and winter blue.

Why prices move
January–February, cheapest: few buyers after the holidays, and dealers still clearing the year's stock.
March–April, rising: tax refunds arrive. Cox Automotive calls it the "spring bounce": used sales traditionally peak just after refunds go out.
May–August, dearest: the busiest buying season. iSeeCars found the fewest below-market deals in May, June and July.
September–December, falling: demand cools, new model years arrive and trade-ins follow, and dealers chase year-end targets.
Fuel prices can override the calendar. In the third quarter of 2026 high gas prices pushed up used EV values while big pickups and SUVs lost value, per Cox Automotive.
Going by the government's used-car price index, January and February are usually the cheapest months, about 1.9% below the yearly average, followed by December. iSeeCars, which looked at over 40 million used-car sales, also found the most below-market deals in January.
What is the worst time to buy a used car?
Summer. Prices usually peak in August, about 2.5% above the yearly average, and iSeeCars found the fewest deals in May, June and July.
Why do used car prices go up in spring?
Tax refunds. Cox Automotive, which runs the Manheim wholesale index, says used-car sales traditionally peak just after tax refunds go out, a 'spring bounce' that lifts prices in March and April.
Are holiday sales good for used cars?
Some are. iSeeCars found the most deals on Martin Luther King Jr. Day, New Year's Day and Presidents' Day, and the fewest around July 4, Juneteenth, Father's Day and Memorial Day.
Does the season matter more than the car?
No. The seasonal swing is about 4% of the price. Picking a more reliable car, or one that holds its value, usually saves far more over the years you own it, so compare the cars first and then time the purchase.
