People always driving convertibles. Full House, Thelma and Louise, 48 Hours, Interview With The Vampire,etc. The list goes on and on. I realize it lets you see the actors, but these people usually live in a big city. You leave that thing alone on the street and it is going to get trashed. Plus, riding in a convertible is a pain in the butt. You can't hear anything for the wind, and just forget about your hair. It might be fun as a novelty, but after about a half hour you get tired of it really quick.
I've never known anyone who uses a convertible as their only car. Its usually their "play car" for Sunday afternoon drives or something like that.
