Finally joined the BMW CCA after many years of owning and enjoying BMWs. Currently have an M240i convertible and just purchased a '91 850i that has been sitting idle for at least 4 years. Always admired the looks of the 850 and when this opportunity presented itself, I jumped at it. Any 850i owners out there with advice? Currently working through problems caused by inactivity with my local BMW dealer. Plan to do what I can myself once the car is running.
