@Grivusangel -- I know what you mean. I don't normally go places where all they have is valet parking. I can't afford those places. A little too rich for my budget. But I do appreciate it when I need to use it.
I have a small car, and it's not a luxury model, by any stretch of the imagination, so it's not at all a target for thieves for anything in it. So I don't generally worry about my car's safety, but if it's a dodgy part of town, and valet is available, like you said, it's a little bit of insurance to make sure your car stays safe.
