The rear tires on my 1987 325is are "bowed" out at the bottom (I think the mechanic said they were "toed out"). I got new tires put on it and the guy said he would adjust the camber to straighten them out. But, half-way through the process he came to tell me that the car had no camber adjustment for the rear wheels. I have had it to two different "german car" repair shops and neither of them knew what was happening. Does anyone here have an idea? Thanks for any help!

Do you have lowering springs on it? That can cause a negative camber angle. And if not,did they investigate your shocks? If your shocks are bad it could definatly cause some sagging problems.
