What really makes a mess of things is when people drive into a parking spot front end first and run up onto a curb. Our car is scraped up underneath but I guess they never got as far as the air dam. Dale and I always back into parking spots and don't have the problem. With a little experience, we've eliminated much of the scraping by where we go and angling into irregular driveways. A friend just bought a lowered Corvette and the big stipulation in the deal was that it had to be put back to stock height. Unless you are going to be racing, the lack of ground clearance is just a royal pain some times.
