|Saw this M3 advertised in San Carlos, Calif. The ad states: "This 1988 M3 has been modified for track duty by the BMW performance tuning company Dinan, based locally out of Mountain View, CA. With over $20,000 in receipts, this weekend warrior runs smooth and handles like it was on rails. A full engine rebuild was done by Dinan and only 6k miles have been added to the odomter since. Suitable for the street, but built for the track, this M3 is perfect for someone looking for a track-ready car that needs nothing."
