well he disclosed the track usage but what about the autocross usage? Someone who has ventured onto the track at least once has probably made at least one appearance to a local autocross club. Four track events more so.
Track usage isn't too bad since you're generally trying to drive smoothly with minimal abuse on the car. Autocrossing is completely different, the car is jerked around severely, more wear on the brakes, tires, suspension, etc. The engine isn't really affected since its designed to work best in these conditions but I wonder how the gear box/trans migh be affected sometimes since all of the work is done in second gear or speeds up to 80mph. If the lot is crappy and full of debris and that micro gravel there could be some cosmetic issues like chipping near the wheel wells, front and rear bumpers and hood. Many people tape up their cars because of this particularly when using r compound tires that suck up everything on the black top and kick it back onto the paint. One autocross here and there is probably no biggie but someone who has done a whole season's worth of autocross races, year after year might cause me to check out his maintenance habits...all mileage is not created equal.
