I'm going to admit, I do put my X3 through a car wash. Up here in MA we are trusted to drive our owns cars into the car wash, I think I'd not let someone else drive it in.
My previous car was an E90 and it never saw a car wash in all the time I owned it, and that was the difference, I owned the car. The X3 is a lease and for some reason it threw a switch in my brain that its not my car and I am less caring about it. Sorry in advance for all those I upset
