Bottom line is...the general public has NO respect for the personal property of others. I always end up walking a long way because of where I park...in places where it's virtually impossible for a shopping cart or a carelessly opened car door can get me. Well, hey..I'm getting exercise too. It works if you commit to it...the Altima I traded in on my 3 was in PERFECT shape because everywhere I went, nobody could get close to the car (unless the were INTENT on doing so - on that front, I was lucky). Sorry about the dents, man..that really bites. I think I rather someone smack me than hit my car - at least I can hit back.
