I called and ordered through Circle BMW, which sells parts and accessories at a hefty discount. Their customer service is second to none, and they ship very fast. The OEM rack is actually cheaper than the Thule version, and is almost exactly the same thing (Thule makes the OEM rack). The base rack for the E90 costs $175 and I believe is part no. 82710403104 (you'll probably want to call to confirm and place your order).Yeah, I have ski/snowboard attachments, but I agree that just folding down the seats is way easier. Where did you get your BMW roof rack from? Did you have a cheaper than dealership source?
