Salvage and repairable vehicle auctions can be a great way to buy a car for well under retail. They can also be an expensive lesson. The difference usually comes down to one thing: knowing your total cost before you bid, not after.
Every cost between the bid and the road
- The hammer price. What you bid and win.
- Buyer fees. Auctions charge a fee on top of the winning bid, usually on a sliding scale by price. It varies by auction, by your membership level and by whether you pay online or in person.
- Extra auction fees. Gate or loading fees, environmental fees, online bidding fees and title or document fees can all apply.
- Storage. Most yards give you a short window to collect. After that, daily storage charges start.
- Transport. Towing or shipping from the yard to your shop, which can be significant over long distances or across the border.
- Repairs. Parts, paint and labour, plus a buffer for the damage you could not see in photos.
- Inspections and paperwork. Depending on where you live, a salvage vehicle may need a structural or rebuilt inspection and a safety certificate before it can be registered again.
- Taxes and registration. Sales tax and plates at the end.
The max-bid formula
Work backwards from what the car will be worth when it is fixed:
Max bid = expected value after repair − repairs − transport − inspections and paperwork − taxes − your margin − auction fees
The catch is that auction fees depend on the bid itself, so the last step is circular. That is exactly the calculation AuctionCalc automates: it finds the highest bid where the fees and every other cost still leave your margin intact.
A quick example
Say a repaired car would sell for $14,000. You expect $3,500 in parts and labour, $400 for transport, $300 for inspections and paperwork, and you want at least $1,500 profit. Before fees and taxes, that leaves $8,300. Once the auction’s buyer fee and your local sales tax are taken out of that, your real maximum bid will be noticeably lower. These numbers are only an illustration; real fees depend on the auction and your account.
Four habits of buyers who win
- Check the auction’s current fee schedule before every sale. Fees change.
- Decode the VIN to confirm the exact trim, engine and model year.
- Add a repair buffer for hidden damage. Photos rarely show everything.
- Set your max bid before the auction starts, and stick to it.
