"BMW rack works well. Just remember to take the bike off before driving into the garage. I was disgusted after I destroyed my $4K bike, my 1 year old 335i, and my garage door.The amazing part is the roof of the car was fine beside the part where the rail hit the edge of the roof line and window. The attachments to the car had no damage and never touched the top of the car. Very well designed rack system that prevents the rack from touching the car, even with an idiot behind the wheel driving too fast into his garage."
