After spending 4 days going through snow, slush, and mud (lot of dirt roads around here) to my local ski areas, I headed to the airport to go on a trip with the family. Because each day was so full and because as soon as you wash the car in these conditions its dirty again, I drove to the airport with a dirty car. While I was away I had the valet airport garage detail my Model X inside and out. The inside looked good, but new scratches I had never seen showed up? Based on how they look, how do you think I got these scratches. Note: before I started the ski week, I had washed the car in a touch-less car wash and the scratches were not there.
