Not for a lot of dealers… KKB is for the public, most dealers use a different book…
Most dealers do not use KBB for trade-in (wholesale) values . Instead, many rely on National Auto Research’s Black Book or the Manheim Market Report, neither of which is available to the public. More important, both tend to skew lower than KBB in wholesale pricing.
Their resale prices are also higher then KBB on top of trade in being lower then KBB… I used to have access to them years ago…
