I remember going to Road America for a SCCA race in 2001, we showed up Thursday evening and the Porshce Club had just finished up a track day and were packing up. A guy had brought his then-new Turbo to the track. The car had 4000 miles on it, and he stuffed it into the barriers, bounced back onto the track, spun and stuffed the other end back into the barriers. End result was the car left the track about two feet shorter than when it arrived!!!!
Keep posting the track day stories! Its fun seeing the X5 and the other sweet rides out there!
