Well, my uncle still have the X5 in the garage. I've had 325,635L, 635csi and 735; they all had many problems. The BMW service department is the worst of all dealerships. The brand new 635L I had for 18 mos. was in the shop for 10 mos. The 635csi I still have but rarely gets out from the garage because it has a faulty driver's seat. It is not adjustable anymore. I've taking back to the dealership at least 15 times and the problem returns after about 2 months. The car also over heats during lacal driving and all the dealership I went to said that they couldn't fix the problem. The 735 had a leaking AC for the entire 3 years I owned it; yeah, the dealers couldn't fix that neither. Ever since I start driving Toyota/Lexus, I've never been to the dealership for repair. For me, Lexus' are far better cars than BMWs. BMW:chairshot:Lexus
