Where do I find my VIN?

On the driver's side of the dashboard where it meets the windshield, inside the driver's door jamb, or on your registration or insurance documents.

How the price is found

One car. A room full of buyers. Twenty-three hours.

A trade-in quote is one buyer's opinion. An auction is the market's. Approved dealers see the same record of your car and bid against each other for it — you see what that competition is worth before you decide anything.

The offer sequence above demonstrates how AutoHouseIQ works. It is not a live auction and contains no real bids, vehicles or dealer activity.

Why competition

An instant offer is one buyer's price. Competition shows you the market's.

We start with an estimate from the best evidence available for your car — dealer auction results where they exist, and similar cars advertised for sale where they do not. Either way the estimate says which it used. If you carry on, approved dealers bid for the car based on what it's worth to their stock, their customers and their market. You see where the bidding lands, and only then decide.

How it works

  1. 01

    Build the vehicle record

    Enter the VIN, mileage, condition and photos. Every dealer bids from the same core vehicle information.

  2. 02

    Dealers compete

    Approved dealers bid against each other for your car in a 23-hour auction.

  3. 03

    You decide

    Take the strongest offer or walk away. Selling remains your decision.

One car. One vehicle record. Every dealer bids from the same information.

See every step

Dealer competition

One car. One record. Dealers compete.

Every approved dealer sees the same vehicle record and bids in a timed auction. Bidders stay anonymous — to each other, and to you until you accept — so the result comes from competition, not from haggling.

A schematic, not a live auction — no real bids, amounts or dealers are shown.

Sell with confidence

Clear information. Fewer surprises.

The car is described once, dealers bid on that record, and you stay in control from the first estimate to pickup.

01

Show the car honestly

Normal wear is normal. Disclose marks up front so dealers price the car from the same condition record.

02

Stay private while dealers bid

Dealers see the vehicle, its condition and a general location. Your name, contact details and exact address stay private until you accept an offer.

03

Know what happens next

After you accept, the agreed price and condition record are locked. We guide payment and pickup, and any material undisclosed issue needs evidence and your agreement before the price changes.

What you get back

A number, and where it came from.

Every estimate says what produced it — dealer auction results for your VIN and mileage, not an advertised asking price, and never an offer.

Questions sellers ask

Is the estimate free?

Yes. Getting an estimate costs nothing and doesn't commit you to anything.

Do I have to sell my car?

No. You can stop at any point, and you're never obliged to accept an offer.

Who can bid on my car?

Only dealers approved by our team who meet our bidding requirements. Our team reviews each dealership's business and license details, and the person responsible for the account, before it can bid.

What happens after I accept an offer?

The sale opens inside AutoHouseIQ. The agreed price and condition record are locked, the buying dealer's business name and contact details are shared with you, and we guide both sides through payment and pickup. If there is a lien, lease or title issue, we do not promise an outcome. Our team reviews the details before the vehicle can be offered to dealers.
