| I'm sorry to say this & dont mean to be rude but this may teach you not to use Car washes (its envitable that it ill damage your car in som way) -as said above if your mini is your pride & joy DONT USE A CAR WASH
I hate the things & they should be banned
Dont you have a hand wash mob near you in the supermarkets or a like
Ok got that off my chest
Go back & double check what is displayed BEFORE YOU do anything - most places so have some form of disclamier
Hope you get it sorted
Good luck |
