Copart and IAA (Insurance Auto Auctions, now IAAI) run the two largest salvage and total-loss auto auctions in the United States. Copart lists more inventory and has a broader public-buyer pool. IAA tends to carry more clean-title insurance cars and gets stronger prices on luxury and late-model vehicles. Most professional buyers use both — the right choice depends on what you are buying and who you are.
Quick answer
- Inventory size: Copart wins. Roughly 175,000 vehicles available globally at any time vs IAA’s ~150,000.
- Public access: Copart is easier — register as Basic ($59) or Premier and bid same day.
- Clean-title share: IAA has more non-salvage insurance returns, lease pulls, and dealer trades.
- Luxury and late-model: IAA tends to pull higher prices and better inventory.
- Fees: both charge buyer’s premium, gate fee, and storage. Copart’s public-buyer fees run higher.
Who can buy from each
Copart sells to the public in most US states through its Basic membership. You can register, get approved, and bid the same day. Some "Dealer Only" lots are restricted, but the bulk of inventory is open to public buyers.
IAA historically restricted bidding to licensed dealers and rebuilders, but now offers public access through partner sites such as Auto Bid Master, SCA, and JS Cars. You bid through the broker; they hold the dealer license. That means an extra broker fee on every purchase.

Which one for which job?
Buy from Copart when
- You want the largest possible inventory, especially trucks and SUVs.
- You are a US public buyer who wants to bid directly without a broker.
- You are looking for parts cars, mechanical-only damage, or rebuild projects.
- You need same-day registration to bid on a vehicle ending soon.
Buy from IAA when
- You want clean-title insurance returns or off-lease vehicles.
- You are sourcing late-model luxury (Mercedes, BMW, Audi, Porsche).
- The specific vehicle you want is listed there. (IAA gets exclusivity from certain insurers — Allstate, USAA, GEICO.)
Fee structure: what you actually pay
The bid is only the start. On a $5,000 hammer price, the all-in cost typically lands around $5,800–$6,400 before transport. The breakdown:
- Buyer’s premium: tiered by sale price. On a $5,000 win, expect $400–$600.
- Gate fee: $79–$99 per vehicle.
- Documentation / title fee: $20–$70.
- Internet bid fee: $59–$129 if you bid online.
- Broker fee (IAA only): 4–8% on top, charged by the public-access broker.
- Storage: 2–3 day grace, then $20–$30/day.

Title types you will see at both
- Salvage / certificate of destruction: totaled, requires inspection to retitle.
- Clean / non-repairable export: some clean-title cars are flagged export-only.
- Parts only / certificate of title (parts): cannot be retitled in any state.
- Bill of sale only: no title — usually parts-only.
- Rebuilt / prior salvage: already retitled after repair.
Key takeaways
- Copart wins on raw inventory and public-buyer accessibility.
- IAA wins on clean-title insurance returns and luxury/late-model pricing.
- Public buyers pay more on IAA because of broker fees on top of auction fees.
- Always price the vehicle independently before bidding — auctions reveal cost, not value.
- Read the lot’s title type. Some "deals" are export-only or parts-only and cannot be registered.
