My wife and I just bought a 2005 X3. I was wondering what I should do in terms of car wash, wax, etc. I've seen all kinds of detailing hints on bimmerfest, but was really wondering if I need to "clay" the vehicle, or just wash it and throw a coat of wax on....

At a minimum I think I will put a coat of wax on the rims...they tend to collect brake dust.....

Thanks!
