Watch your car's value over time

Every month, Offer Watch estimates your car's current value based on projected mileage from regular use, conditions and history reported in your most recent offer, and the current used car market.

Offer Watch provides updates on your car's estimated value every 30 days after your initial offer, or on your dashboard whenever you want. These estimates help you better understand your car's value over time by tracking market trends and typical usage projections. You can use Offer Watch for free, as long as you want. Once you're ready to sell, confirm your car's details and condition to redeem your offer.

Offer Watch estimates can't be used to sell your car to CarMax. When you're ready to sell, you'll need to turn your estimate back into an active offer.

Take a few minutes to update the current mileage and conditions, and we'll give you a fresh, active offer you can take to your nearest CarMax. We'll handle the rest.
