No kidding. I'm absolutely amazed how lax they are! They refunded me $760 for the sports package since I couldn't get a sport steering wheel (with the driver assist package). A simple footnote on the build website would fix the problem...still hasn't happened. The BMW website is higher quality and they maintain it. I must say though, I enjoyed receiving the refund and my e350 is great.MB needs to keep their website more updated.
