Sell My Car STL vs. KBB Instant Cash Offer.
The thing most sellers miss: Kelley Blue Book does not buy cars. That offer is a referral to a dealership — and we are what the referral leads to.

The honest rundown
How the KBB Instant Cash Offer actually works
You enter your car's details on Kelley Blue Book and receive an Instant Cash Offer with a certificate. What has happened behind the scenes is a lead hand-off: the offer is underwritten and honored by a <em>participating dealership</em> near you, which then inspects the car and finalizes the number. KBB is the brand on the certificate, not the buyer of your car.
This is not a scam — it is a lead-generation program working exactly as designed, and the dealership at the end of it may well be a good buyer. But it is worth knowing that you are being routed, that the routing is paid for, and that the number on the certificate is subject to the same in-person revision any sight-unseen quote is.

The comparison, in plain rows
Fair is fair
Where the KBB route honestly wins
It is a useful piece of market research, and it is free. If you want a rough sense of your car's wholesale neighborhood before talking to anyone, the estimate is a reasonable starting anchor — Kelley Blue Book has decades of data behind it.
And if the participating dealer inspects your car and writes you a number that beats both of ours, that is a good sale and you should take it. That written, inspected offer is also precisely what qualifies for our $300 guarantee, so running the KBB route first costs you nothing.
Our side of the ledger
Where we win
- One fewer party in the transaction: the company that appraises your car is the company that writes the check.
- Two offers rather than one, including a profit-sharing option that targets retail instead of wholesale.
- No sight-unseen anchor to be negotiated down from — we look at the car and then commit.
- If the referred dealer's inspected offer is higher, we pay $300 over it.
The honest verdict
Use the KBB number as a reference point, not as an offer. Then get a real appraisal from a company that buys cars directly, and compare two actual numbers against the estimate rather than one estimate against itself.
