i have been lucky so far. i have nicked the curb twice, once at home in the driveway because i have to park at this ridiculous angle because my father's expedition takes up 90% of the driveway, and again while i was at work. Both times i count my blessings that it only hit the tire and not the rim. I just rubbed the tire down a little and you can't even notice.
But again, i am like you guys, i notice every little dent/scratch on my baby. except for the ones that were there the day i bought her :so i was too excited to notice them....
