Hi i am a new member to m6board however i have been looking around here for awhile. My dad owns a 2008 m6 convertible which he bought used last May. When he bought it it had 15,000 miles and was on its second set of tires. We did not know the heads up display was not working properly when we bought it (it would not show m view). During the summer it had been in the shop several times for a restraint system malfunction code, strange clunking sound when shifting, convertible top not locking, brakes, and heads up display. The convertible top was dismissed as cold weather messing up the sensors. Clunking was supposed to be a bad rubber piece on the u-joint, however when it was replaced it did not help but resetting the clutch did. the clutch still needs to be reset on occasion to prevent it. restraint system code happened twice resulting in two weeks in the shop. currently the car has 30,000 miles on it. Is this a usual amount of service for one of these cars. By the way the car has been put away since thanksgiving.
