Used Car Market Statistics: How Big It Is, How Fast It's Growing & Where It's Headed

Americans bought roughly 38 million used vehicles in 2025 — about 2.4 times as many as they bought new. The used-car market moves ~$1 trillion in annual sales, more than 1.3× the dollar value of the new-car market, and it does it almost invisibly. Every headline that talks about "the US auto market" is talking about the smaller, louder 16-million-unit new-car market. The 38-million-unit used market is where most Americans actually buy and sell cars — and 2025 was the first year in five that it behaved like it used to.

How big is the US used car market?

The US used-car market is roughly a $1 trillion annual industry, moving about 38 million vehicles a year. At an average retail price of ~$27,000, that works out to about $1.03 trillion in transactions. Cox Automotive estimates 2025 full-year used sales between 37.9 million and 38.5 million units — retail sales grew about 2% year-over-year, after averaging near-flat performance since 2022.

Used cars vs new cars: which market is bigger?

The used market is bigger on every meaningful measure except revenue-per-transaction. By unit volume, Americans buy about 2.4 used vehicles for every new one (~38M used vs ~16M new). By dollar value, used still wins — ~$1T vs ~$784B — but only by about 30% because the average used price ($27K) runs about 55% of the average new price ($49K). Where new-car sales are volatile (they swung from 17M pre-pandemic → 13M during 2020–2022 → 15.9M in 2024), used-car sales are structurally steady: they've stayed in the 36-40M band for the better part of a decade.

What is the average used car price in the US?

The average retail used-vehicle price in the US ended 2025 at about $27,000, per Edmunds and Cox Automotive tracking. That's down modestly from the early-2022 peak (~$28,500) but well above the pre-pandemic average of ~$20,500 in 2019. The Manheim Used Vehicle Value Index — the wholesale benchmark that leads retail prices by ~90 days — closed December 2025 at 205.5, +1.8% year-over-year, and just under its long-term trend growth rate. Meaning wholesale prices are once again depreciating normally.

How has the used car market grown since 2020?

Not by unit volume — by price. Used-vehicle unit sales actually declined slightly from 2020 to 2022 (from ~39M to ~36.5M) as pandemic supply chaos shrunk the pool of available used cars. But wholesale used prices roughly doubled in that window (MUVVI 141 → 259), so market dollar value climbed even as unit volume fell. Since 2023, unit sales have stabilised in the 37–38M range, prices have unwound about 20% from the 2022 peak, and the market has settled into a new post-pandemic equilibrium.

What's the forecast for the US used car market?

Technavio projects the US used-car market will grow by roughly $31.7 billion between 2026 and 2030, at a compound annual growth rate of about 4.7%. Cox Automotive's forward outlook for 2026 assumes "normal depreciation" resumes in the wholesale market and points to rising EV influence in used inventory (as the 2020–2023 EV wave ages into the second-owner market for the first time). The main open question is whether the 3–5-year-old inventory shortfall from the pandemic keeps holding a price floor above trend, or whether it finally unwinds.

Where do Americans buy used cars?

The used-car sales channel splits roughly three ways. About 45% of used vehicles are sold through franchise new-car dealers handling their trade-ins and certified pre-owned inventory. About 30% go through independent used-car dealers — from national chains like CarMax and Carvana down to single-lot used-car lots. The remaining ~25% are person-to-person (P2P) sales between private parties, often mediated by online platforms like Craigslist, Facebook Marketplace, and specialist listing sites.

How many used cars have a hidden history?

This is the section every rosy market-size report skips. The 38-million-unit US used-car market includes a substantial slice of vehicles carrying histories buyers don't know about:

• ~450,000 vehicles per year are sold in the US with rolled-back odometers, per NHTSA estimates — costing consumers roughly $1 billion annually.
• ~500,000 vehicles per year are branded salvage or rebuilt, and a significant share get "title-washed" as sellers move them across state lines to re-title with clean paperwork in less-strict jurisdictions.
• ~250,000+ flood-damaged vehicles re-entered US dealer inventory after Hurricane Ida alone; NICB tracks similar spikes after every major flood event.
• 1M+ vehicles per year are actively stolen in the US, and a fast-growing minority are VIN-cloned before resale to unsuspecting used-car buyers.

Surveys consistently find that roughly 60–70% of used-car buyers skip a full vehicle history check on their purchase. In a market where used prices have permanently reset upward, that's a substantially bigger dollar exposure per skipped check than it was five years ago. Running a free vehicle history lookup or a branded title check before signing anything takes under a minute and covers most of the risk surface above.

Which used cars sell the most in the US?

Ford F-Series pickups, Chevrolet Silverado, Toyota Camry, Honda Civic, and Toyota Corolla have dominated US used-vehicle sales rankings every year for the past decade. In practice, the used-car market is a lagging echo of the new-car market from 3–7 years earlier — so what sold well in 2018 is what sells well used in 2025. Used-EV sales are the fastest-growing subcategory in 2025, up sharply as first-generation Tesla Model 3s and Chevy Bolts age into second-owner inventory — see our Electric Vehicle Statistics report for the full US EV market breakdown.

Why do sources disagree on the size of the US used car market?

"The US used car market is $X" reports can vary by a factor of two depending on definitions. The three big variants:

• Retail-only vs retail + wholesale. Retail (dealer-to-consumer + P2P) is ~$1T. Add wholesale auction volume — vehicles moved between dealers, trade-ins going through auction — and total transaction value roughly doubles. Manheim and Adesa alone auction ~10M vehicles a year that show up in the wholesale total but are the same cars that appear in retail totals later.
• Franchise + independent dealer sales vs "all used sales." Industry reports (like Technavio's $72.2B 2024 figure) often measure only third-party channel dealer sales, which excludes P2P entirely. That produces a much smaller number than "total used vehicles changing hands."
• Unit sales vs registrations. The 38-million-unit annual figure is Cox Automotive's estimated retail transaction count. FHWA vehicle title-transfer data captures a slightly different number — every ownership change filed with a state DMV, including inheritances, gifts, and business fleet transfers.

For consumer-facing coverage, "38 million used vehicles sold to consumers per year at ~$27K average price = ~$1 trillion market" is the honest number. Anything much bigger is counting wholesale + retail together; anything much smaller is one channel only.
