Bought this car at age 21 and drove it very hard. Original clutch lasted until 155k. No other problems other than typical wear and tear. Performed very well for a 1.8 litre. Drove a friends 325is with 100k less miles and the 318is is just as quick as long as you keep the RPM's up (the 325is did have a greater powerband). Comfy car, fun to drive, not the best in snow but made it through 4 winters with heavy snow never going into the ditch. 190k on it now and still getting average of 27.5 MPG driving in rush hour traffic. Engine is a little tired now but it still runs very well. Overall great car.
Emergency toolbox in trunk, ease of using emergency jack to raise vehicle. Air sealing windows. Tight handling. German engineering.
