1990 325i Convertable
 

I own a 1990 325i Convertable that has sat in a home garage for some 8 years or so, without running. I recently, within a week, had the car in service and now, after a new battery, fuel pump and fuel tank as well as a few additional service points, have the car runnng again. Now that the car is running, and it runs fairly strong after sitting for so long, the service facility suggest I drive the car for a few months to let everthing settle "into place" before giving the car a full checkup. Anyone have a similar situation and have any suggestions for me? Also, where can I find quality replacement parts and accessories for the car? Anyone know of a decent stereo and CD player for this older car? By the way, the car has only 113,300 miles! Can I expect to drive this car much longer?
