If KBB is $3.3k in excellent condition then theres your answer. No car with 207k on the clock will be in excellent shape. Sorry I don't care if he's a mechanic or not no car will ever be in excellent shape at the mileage. There's going to be flaws on the exterior and the interior I can promise is going to show some wear and tear for sure! The guy thinks that just because it has some ugly aftermarket part like the projector halo headlights, altezza tails, and the konig wheels sounds like this guy is living in the Fast and Furious era still. Also sounds like he has some fun with it if he's telling you about throttle response and passing people on the road.
It may have every single maintenance record, which is good but if KBB is saying its $3.3k in excellent condition then sounds like its time for negotiating. I would off him $3000 for it, but if it were me I wouldn't even look at it. 200k is alot of miles I don't care if its got a new motor and tranny other things are going to give out. $5 says the heated seat doesn't work, rear view auto dimming mirror doesn't work, and the HUD doesn't work 100% of the time.
