I have an '87 325is For Sale with a handfull of very nice upgrades. As you probably already know, the "is" comes with the same: Seats, Steering Wheel, interior, and several other things as the M3. The biggest difference is the suspension, but I have upgraded my shocks to Billsteins. I believe that the 325is is a better daily driver since the i motor requires less service and is less finicky. I am located in Northern California, so this car is rust free and in excellent condition. I have upgraded the car: Suspension, Chip, Intake, Stereo system, Clifford Alarm, European Headlights, and more. Come take a look and make me an offer!! Click on the link below for a picture.
