Lol I'll take 2 at that price. I've never seen a 33 GTR that low priced, even from an import broker. Stay away from cheap GTRs. Theres a reason they're cheap and none of them are good.
I'd try and go private since you will get it cheaper than at a dealer. Highly unlikely that it has genuine k's on it but don't stress about it too much. By on condition of the car not how many K's it has done. RBs will keep going strong for a long time as long as they are serviced properly.
