twin turbo, twin everything = higher maintainence/replacement costs. being 4wd + twin turbo puts the drivetrain and GB under a lot more stress than a Rwd as well....a couple of years does make quite a difference in Kms wise...furthermore...regardless of how stock a GTR comes when it lands from japan, you can bet your left nut that it would have been thrashed or pushed hard in their lifetime...and rightfully so because that was what they were built for!
