I've owned this wonderful car for about 2 years. It appears though that the rear wheels are bowing out. I suspect springs. Car only has 70K. Can someone give me an idea as to what the typical problems are? TIA

Common problems can be found at www.E38.org read everything there and questions about 7s will be answered.

If your car is a 740i then I agree with you that the springs are probably shot very prematurely, but if your car is a 740iL then there's probably something wrong with you LAD self-leveling system.
