Finally got around to trying out that Special Stage Route X wall glitch. Gonna do some riding around inside all the various walls and see what new stuff I can find at the X... For those interested use the Nissan GT-R Black edition '12 only, then ride along at very high speed rubbing the side rails. I've tested other areas and they work also with patience... Edit Added... The only reason my car shows no damage is that I turned off temporarily in the options menu arcade mode the visible damage. If you want to take photos and leave the visible damage on in the option menu arcade it will make the Nissan look really bad with damage, especially with the white one the sparks create black burn marks from sparking against the rail all over the car.
