Is this the really big one for the 850 Turbo? If so wat needs to be done to the car? some of the things that will be changed due to problems in the car, is the gear position lights, the air hose that regulates the flow of air into the car when the fan is off is broken and dangles around in there. Possibly a bad rear suspension that squeaks, and the sun roof needs a little oiling. Ride needs to be sealed up a little more because of major wind noise, and that's about all I can think of. Oh also that we'll probably get the guys to make sure the car has less rattles.
