Won an auction you can't close?
Life happens between the hammer and the pay-by date: a deal falls through, a spouse says no, the inspection turns something up. Before you disappear on the seller, know what's at stake and what your options are.
What walking away costs
Bids on the major sites are binding. On Cars & Bids, a winner who doesn't follow through forfeits the buyer's fee (5%, $250 minimum and $7,500 maximum) and is permanently banned. Other sites have similar rules, and the fee is usually charged to your card when you win.
Your options
- Talk to the seller and the platform right away. An honest early call is better than silence, and some deadlines can move.
- Close and resell. Buy the car as agreed, then sell it on. You keep your standing with the platform.
- Find the buyer who missed it. On 2ndBids, buyers post the exact cars they missed, often offering to reimburse the winner's buyer's fee plus a premium. Where the platform's terms allow, they can take the purchase over, or buy it from you once you've closed.
Check your platform's rules on transferring a win before you promise anything. Some platforms require the sale to go through them.
Common questions
What happens if I win a car auction and don't pay?
You typically lose the buyer's fee and may be banned from the platform. The seller may also have claims against you. Check your platform's terms.
Can someone else take over my winning bid?
It depends on the platform's rules. A common safe route is to close the purchase yourself and sell the car on to a buyer who wanted it.
