Is the PP KBB value of a car the listed price or out-the-door price (after taxes, registration, etc).?

I'm interested in buying a used car from a dealership. I was able to haggle the listed price down to $16K, but the dealer won't go farther down. The out-the-door cost after tax and other fees is about $17,700. The price on KBB is $16K for good condition, $17K for excellent (private party). If the price on kbb is supposed to be representative of the listed price, I should be getting an ok deal. But not so much if it's the out-the-door price. So which is it? The car is in like-new condition, btw, according to my mechanic, but there is no warranty included/offered from the dealer, and no other extras offered. I don't know if this matters, but this is a rather rare car to find (not made anymore).
