Dealer-only auctions like Manheim, ADESA, ACV and CarMax sell cars that franchise and independent dealers don't want to retail, plus off-lease returns, fleet and rental cars, and bank repossessions. Salvage auctions like Copart and IAA mostly sell vehicles insurance companies have declared total losses, along with some donated, recovered-theft and clean-title cars. Public auctions sell government surplus and unclaimed tow-yard vehicles. The source tells you a lot about the car before you open the condition report.

The main sources
| Source | Where it's sold | What to expect |
|---|---|---|
| Dealer trade-ins the dealer won't retail | Manheim, ADESA, ACV, CarMax, EBlock | Older, higher-mileage or cosmetically rough. Some are fine cars that didn't fit that store |
| Off-lease returns | Manheim, ADESA, OVE, often offered upstream first | Usually 2–4 years old with known history |
| Fleet and rental cars | Manheim, ADESA | Higher miles for their age, often maintained on a schedule |
| Bank and finance repossessions | Dealer auctions | Condition varies widely. Check for missing keys and deferred maintenance |
| Insurance total losses | Copart, IAA | Salvage or nonrepairable titles; flood, collision, theft recovery, hail |
| Donated vehicles | Copart, IAA and charity auctions | Mixed condition |
| Government surplus | State and local public auctions | Fleet cars with records, sold as-is. See How do police and government auctions work? |
| Unclaimed tow-yard vehicles | Lien sales open to the public | As-is, little or no history |
Why the source matters
- It predicts condition. A 3-year-old lease return and a 15-year-old trade-in that a franchise store wouldn't keep are different bets.
- It decides the title. Insurance-loss cars usually come with a salvage certificate. See How does a car get a salvage title in California?
- It decides your protection. Dealer auctions offer arbitration and post-sale inspections; salvage and public auctions are mostly as-is. See How does auction arbitration work?
- Check the history anyway. Run an NMVTIS report from an approved provider, and use Carfax or AutoCheck as a supplement.
From experience (Garrett Eddings, professional opinion): Auction inventory is mostly cars somebody else already decided not to keep. That's not bad. It's just a reason to read the report, book out the car and buy it at a number that still works after fees and reconditioning.
Frequently asked questions
Where do dealer auction cars come from?
Mainly dealer trade-ins the dealer won't retail, off-lease returns, fleet and rental vehicles, and repossessions.
Where do Copart and IAA cars come from?
Mostly insurance companies selling total-loss vehicles, plus donations, theft recoveries and some clean-title cars.
Are auction cars bad?
Not necessarily. Condition depends on the source and the individual car. Read the condition report, check the history and use the auction's post-sale inspection when it's offered.
