Hi guys, My car died last week so I am in need of a new car. My mate showed me a skyline, always have liked the cars, and now want to buy one. I was googling for information on the dealer who is selling this particular car and stumbled onto a thread containing the nissian FAST system, which allows the VIN Number to be checked. The VIN for this particualar car is listed as rb25 060551a on the site. How do I go about checking this? Any help would be greatly appreciated. Cheers
