What the hell is that supposed to mean? I guess if he's some kind of licensed independent dealer then maybe it comes with "dealer papers" but I don't see how those would increase the value of the car.
If you're looking at buying the thing, you shouldn't mention what KBB says anyway. You don't need to say "well I looked at the price on thus-and-such" to qualify your offer. Just make an offer.
No clue what it's supposed to mean, that's what he put in the ad. Well im gonna go check it out Friday. He said he's gonna bring the dealer plates so I can test drive it and if it's in as good condition as it shows in the pictures I'm going to make him a offer.
