Bid. Sell. Watch. Simple.
GM Vault is the marketplace built only for GM collector vehicles. Here's exactly how buying, selling, and the watchlist work.
Bidding on an auction
- Sign in and add a payment card on file in your account.
- Open any live auction and place your bid.
- We verify your card with one reusable auction hold. Bid as many times as you like without extra holds; if you win, the buyer's premium is charged — this is GM Vault's fee, not a deposit toward the car.
- When the auction ends, the highest bid above reserve wins. Buyer and seller exchange contact info and the buyer pays the seller 100% of the sale price directly.
Bid Goes On (didn't sell? Buy it now.)
If an auction ends without meeting the seller's reserve, the car moves into Bid Goes On for 7 days.
- Listed at the seller's reserve price as Buy It Now.
- The seller can lower the price anytime during the 7 days.
- First buyer to hit Buy It Now wins. Same 5% buyer's premium to GM Vault, full sale price paid directly to the seller.
- After 7 days, the listing closes if unsold.
Watchlist + 30-min SMS alerts
Tap the heart on any auction to save it. Then add your phone number in your account.
- When a watched auction is 30 minutes from closing, we text you the current bid and a direct link.
- Never miss the last sniping window on a car you care about.
- One alert per auction. Manage your watchlist anytime.
Selling your GM
Two ways to sell — both reviewed by a Vault specialist within 48 hours.
7-day live auction. You set the reserve. If sold, the buyer pays you the full sale price directly — GM Vault collects its 5% buyer's premium separately from the buyer.
Tell us your asking price. A specialist responds within 48 hours based on photos, history, and condition.
Trust & verification
- Every listing reviewed by a Vault specialist before going live.
