My car has been at BMW Midtown for freakin 6 days! I came in for very minor work (so I thought). Squeeking steering and a weak battery. The dealer claimed that it has taken them 4 days to diagnose the problems and that parts had to be overnighted. I certainly hope that the techs did not do some other damage to the car and that they are scrambling to order body panel parts.
I didn't get a Malibu as a loaner though. They gave me a 2011 528i which is pretty sweet ride.
