Three words: Bait...and...screw. KBB's "cash offer" will generally be higher than Carvana's. The difference? Carvana will actually PAY YOU CASH for your car. With KBB, you have to take your car to the dealership... and negotiate. (It would be interesting to see if ANY KBB deal is ever actually completed with that value.) Wanna bet they will find enough "imperfections" on your trade-in to reduce their "instant" offer to at or below Carvana's? DO NOT WASTE YOUR TIME WITH KBB's INSTANT-CASH NONSENSE. It should actually be illegal.

Scam website they price vehicles… Scam website they price vehicles extremely low so when you want to trade your vehicle at a dealership they use Kelly blue book to value it but when you buy a truck from a dealership its 10 times higher then what Kelly blue book prices. The only reason it exists is so that dealerships can scam you out of what your truck is actually worth.

Bait-and-switch scam - don't be fooled They gave me an instant price quote online, and when I visited 2 local dealers both of them reduced the price by about 10% even though they both agreed with the condition and all criteria I entered online. The first one added a $1000 "certification fee" and the second one just said they adjusted it because of "the economy". I had gotten the price quote 3 hours earlier. This is a complete BAIT-AND-SWITCH - save your time and don't use it.

Service is reducing trade-in prices Service is reducing trade-in prices. It used to be that consumers trusted KBB to help them determine the fair trade or resale value of a car. Now, what KBB does is provide obscenely low cash offers AND broadcast those obscenely low offers to every dealership in your local area. As a result, you not only get spammed by every dealership, you also lose out on fair offers for your car because ALL of these dealers know that KBB sent you with an obscenely undervalued offer, so they can offer you one or two thousand above that - or even less than the KBB offer - and appear "generous" when, in fact the trade-in value of your car was much higher. Reported this to the FTC. In my case, every other "Book Value" service valued my car at several thousand dollars more than KBB. I also checked around on the used car prices and private seller sales prices of the same model car - again several thousand higher than KBB.

KBB customers are the most uneducated… KBB customers are the most uneducated people ever. Stop complaining about the calls that you are getting from dealers when YOU provided the phone number. Excuses like "I did not know that they will send my information to multiple dealers" are plain stupid especially when there are multiple places on the KBB offer that states that you WILL be contacted by dealers, including in the Terms and conditions at the end that KBB REQUIRES to click on to make sure that you read them! Also DO NOT mark your car as perfect when it is not! 99% of the complaining customers here misrepresented their cars drastically and love to complain when the dealers find out their lies and shenanigans. Play stupid games win stupid prices....
