It is so low, and sticks out there so far, it was bound to get scratched a bit sooner or later. It just happened to you sooner. Definately don't obsess over it. You may notice it, but I doubt hardly anyone else will. If it looks great at 50 feet, don't worry about it at all!
PS, when I park low cars, I like to park into spots that don't have an opposite space if possible, and if they do I prefer to back in. If I don't I have had problems with trucks pulling into spots opposite mine, and pulling right over the bumper/hood because they cannot see it past their own, high hood. I'd rather take my chances with the parking blocks than the hummer drivers! :banghead:
