The KBB Instant Cash Offer is a written offer on your car that a participating dealer redeems, not Kelley Blue Book. You describe the car online, take it to one of those dealers within seven days, and the dealer’s inspection can raise or lower the number before you sell it for a check or trade it in.

Many instant cash offers for a car come from the company that will buy it. KBB’s works differently: Kelley Blue Book builds the number, and a dealer buys the car. Its program terms say Kelley Blue Book and Autotrader “do not redeem Instant Cash Offers or purchase vehicles,” and that the offer is redeemable at “dealers who have paid Kelley Blue Book or an affiliate to participate.” The steps, from KBB’s FAQ and terms:
Getting the offer and using it cost you nothing: “There is no fee to obtain or redeem the Offer,” says KBB’s FAQ. The dealers pay instead. KBB’s terms say they “pay a monthly subscription to participate in and receive leads,” and the same terms let participating dealers contact you about your offer once you ask for one.
A participating dealer is an ordinary dealership that pays to be in the program. KBB’s terms say these dealers “are not owned or operated by, nor are they affiliated with or acting on behalf of, either Kelley Blue Book or Autotrader.” KBB shows you a list of them with your offer, and its FAQ says it will try to find dealers in your metro area. If none appears near you, the terms say to call KBB’s customer service at 1-866-559-5268.
The dealer’s duty is narrow but real. KBB’s FAQ says participating dealers must honor the offer “provided the information and condition you provided when creating your Offer are confirmed to be accurate.” A dealer doesn’t have to pay more than the offer, but the terms say “you are welcome to try to negotiate a more favorable price or trade-in amount.” If a deal goes wrong, the terms make any claim over the sale one between you and the dealer, not KBB.
Two limits apply at the counter. An offer above $75,000 “may not be accepted by every Participating Dealer and may require an additional inspection.” And one person can use the program for no more than three vehicles in any six-month period.
The inspection decides the final figure. KBB’s terms say it may include “paint thickness measurements, a road test, a mechanical inspection, and a review of vehicle history reports and disclosure statements regarding flood, salvage, or odometer discrepancies.” The dealer reports what it finds through the same online tool you used, and the offer “may be adjusted up or down prior to redemption.” On condition, the dealer has the last word: “All decisions of the Participating Dealer regarding the condition of your vehicle will be final.”
So the figure you see online is only as good as your answers. KBB lists what can push an offer outside its trade-in range: “market volatility, rapid changes to the market, mechanical issues, excessive damage, reported issues, aftermarket equipment, modified suspension, or the vehicle’s specific condition.” Describe the car the way a buyer would see it. A scrape or warning light you leave out is likely to come off the number at the dealer, and the terms say false or incomplete answers can void the offer outright.
A lower number after inspection is not a sale. KBB’s FAQ says there is “no obligation to trade-in or sell your car” just because you received an offer. Treat the inspected figure as one written number to compare; it stays open until the end of the next business day.
KBB’s terms list the cars the program “may not be used to sell or to trade in,” and the program is not offered in every area. KBB’s FAQ adds “lack of market data” and “unresolved recalls” to the reasons a car gets no offer at all. The main exclusions, and where each car can still sell:
| Excluded by KBB’s terms | Where it can still sell |
|---|---|
| Salvage or reconstructed (rebuilt) title | Buyers who price branded titles: selling a salvage or rebuilt car |
| Older than 24 model years, or over 300,000 miles | Private buyers, scrap and as-is buyers: getting rid of an old car |
| Worth less than $1,000 by KBB’s valuation | Junk and as-is buyers: what a junk car is worth |
| Under recall, or investigated by a government agency | Ask again once the recall repair is done: checking recalls before you sell |
| Current model year or newer | A dealer appraisal or another instant offer: selling to a dealership |
| Police, fire, livery, taxi or rental history; commercial, exotic or gray-market vehicles; no valid VIN | KBB’s pages don’t say; a dealer or private buyer decides |
| Altered driveline or body, or illegal or non-working emissions equipment | A private sale or an as-is buyer |
| At an auction, or offered wholesale, in the last 45 days | Wait until 45 days have passed, or sell another way |
A car that doesn’t run isn’t on the list by name. But you have to deliver the car to the dealer, and the dealer may test drive it. Nothing on KBB’s pages covers a car that has to arrive on a tow truck, so the dealer decides. For that car, start with our guide to selling a car that doesn’t run.
If the program turned your car away, our buying partner’s sell page says cars that don’t run “can still receive a cash offer” and that, in many states, cars with salvage, rebuilt or missing titles “may still be eligible.” Get a second offer there; it is free and carries no obligation.
For some cars, yes, and KBB is open about the trade-off. Its terms say the offer “may be less than the Kelley Blue Book® Trade-In Value,” and, “though we think the Offer allows for a convenient and easy way to sell your vehicle, it may not be the highest sale price or trade-in amount that you could receive” outside the program. A private sale aims at KBB’s private party value, which its values FAQ puts above the trade-in figure because a dealer has to recondition and resell the car.
It is likely the better deal for a clean, recent, mainstream car that sits well inside the limits above, especially if you are buying your next car from the same dealer anyway. You get a written number before you drive anywhere, you can take it to more than one participating dealer, and you skip test drives with strangers. A private sale is slower: Autotrader’s own FAQ puts the average sale through its private-seller checkout at two to three weeks, and the ad and seller fees cut into what you keep.
It is likely weakest for a car with one of the traits KBB names as reasons an offer can fall outside its trade-in range: mechanical issues, excessive damage, reported issues or modifications. KBB’s pages don’t say how often an inspection lowers an offer, so judge the program by the inspected number you actually get.
Use the seven days to collect other written numbers, then compare them on the same terms: the amount after each buyer’s inspection, how you are paid, and who moves the car.

Not in bills. KBB’s terms say the dealer issues a check once it has a clear title, made out to the owners named on that title. KBB’s Sell My Car page says payment usually comes by check or electronic transfer.
Seven days from issue, and KBB’s values FAQ says Sundays aren’t counted. After the dealer’s inspection you have until the end of the next business day. If it lapses you can ask for a new one, but KBB’s FAQ warns that the amount may change.
KBB’s FAQ says most offers do fall within its trade-in range; the reasons it gives for one that doesn’t are in the inspection section above. The two figures also price different deals: KBB’s trade-in value assumes you are buying another car from the same dealer, while the Instant Cash Offer is priced, in KBB’s words, as “a liquid cash offer to be honored by a Participating Dealer irrespective of whether you are purchasing another vehicle” there. Its terms say the offer may be lower than the trade-in range for a similar car. KBB doesn’t say how much that difference moves the number.
Yes. KBB’s FAQ says to check with your leasing company about the paperwork it requires, and the terms ask for the lease details, including the early termination fee. The dealer processes the payoff; if the lease balance is more than the offer, you pay the difference before the sale closes. Our guide to selling a leased car covers when a sale beats turning it in.
No; under that program the buyer is always a participating dealer. KBB’s separate Sell to Kelley program is covered in our guide to selling through KBB.
