Lol. I can't believe you're even still interested in bargaining with the seller.
If someone was advertising a car for sale with total BS like this guy is, then he's either a scammer, or clueless, and I wouldn't want to be dealing with either of the 2.
Plenty of GTR's for sale, no need to put effort into what seems very dodgy.
Justin911's for example, Only asking something like 21k, and it's in great condition with a few nice little extras...A great base to start with.
Yes he's a mate of mine, but if I was in the market for a 33 GTR I wouldn't hesitate in buying his.
