CarWhere vs KBB

Short answer: Kelley Blue Book's new-car number is the Fair Purchase Price — a market estimate of what buyers are paying, not the dealer invoice. CarWhere gives you the factory invoice estimate and the verified buyer-paid price for your exact VIN, free and with no account. Use KBB for a market gut-check; use CarWhere for the invoice number and a target offer.

FAQ

Does KBB show the dealer invoice price?

Not really. Kelley Blue Book leads with its "Fair Purchase Price" — a market estimate of what buyers are currently paying for a new car — rather than the dealer invoice (what the manufacturer charges the dealer). If you specifically want the invoice number, KBB is not the place to get it; a by-VIN invoice tool is.

What is the KBB Fair Purchase Price?

The Fair Purchase Price is KBB’s estimate of what people in your area are actually paying for a given new vehicle, based on transaction and listing data. It’s a useful market reference — but it’s not the dealer’s cost, and it isn’t tied to your exact VIN or its options.

Is KBB or invoice price better for negotiating?

They’re complementary. Invoice (minus 2%–3% holdback) tells you the dealer’s cost floor; KBB’s Fair Purchase Price tells you roughly what the market pays; and verified buyer-paid data tells you the actual target for your exact vehicle. CarWhere gives you the invoice estimate and the verified buyer-paid number together, by VIN.

How do I get the dealer invoice price by VIN instead?

Use CarWhere’s dealer-invoice-price-by-VIN tool: enter the VIN and get the estimated factory invoice for that exact build free, no account, alongside the original window sticker and what verified buyers actually paid.
