Any known faults to look for when buying a nissan skyline 250gt auto 2002 model car?

It's a sweet car, but don't let the looks fool you. Look on the pillars where the paint meets the rubber. If you see evidence of a repaint, It was repainted for a reason. Spend a hundred bucks an have it checked front to back. That should be a hundred point inspection, thus "guaranteeing" you a reliable car.
