In have a 90 4 matic. the 4 matic is great in the snow, but it can be very problematic, and difficult to diagnose when problems occur. I flipped my test switch for this and have been driving with it disconnect because of the vibrations when making a turn, no one can figure out. It drives great with it off. I will reconnect it in the winter. I have no other problems with car. It runs and drives like its brand new. This is really a solid car. I wouldnt trade it for anything. well...............
