While my 3-series wagon was under warranty, all was well. I didn't mind the repeated trips to the dealership to replace every motor in each of my power windows, or my power steering leak, or a regulator in my AC. However, once the warranty expires the out of pocket cost to replace a transmission, along with lengthy list of repairs that accompanies each regular check up becomes quite irritating. The door panel inserts became dislodged and even the BMW logo on the hood came off. . . TWICE. Too headache and expense for "the ultimate driving machine."
