Hey OP, first time posting here I usually only look for wheels ect in the for sale section, I even registered to maybe help you out since your in the market for a particular car and large sum of money for a second hand car. When looking for a GTR of any year you want all the work done ie; diffs, turbos, bottom end, aftermarket computer ect. You will want to see receipts for these things so you can gauge how old and worn in they are. A Japanese structural report also prior to export is also essential on the "grade" class of vehicle. As mentioned above Iron Chef would be a better way to go.. if you can't wait buyer beware a lot of the ad's are vague and id assume a lot of the owners would be doing their best to mask problems and what not. Alarm bells should be going off when you first look at a car with aftermarket front end, worth 4-5k parts + paint and a stock top block motor.. Personally I wouldn't worry about colour preference and focus on finding a good one 100% get it inspected for twisted chassis and wonky diff's ect.. Also the single turbo conversion on a R34 GTR.. ahaha, if it was my money i'd only be looking for a twin system perhaps even aftermarket or rebuilt internals. I belive HKS had a kit for GTR rb26's? If you really only know as much as your post count suggests about cars, then I would really be taking someone along who knows skylines or looking at paying an importer their premium since its a lot of money to blow on guess work. My advice to you like my friends who love the Nissans, if you cant find a clean Nissan go test drive a RZ Supra or a series 6-7 13b RX7 with receipts backing up it's "condition" til a nice Nissan comes along. Goodluck with your purchase, Sam.
