I came across a very nice ///M3/4 today. It is a 1997 with 47,000 miles. It is Bright Red with Black leather interior. The car has a few mods.They are UUC short shift kit, Dinan CAI,Dinan Stage 2 programming, Strut tower brace, Eibach springs, and Remus exhaust. It has never been in an accident. It also has 18" rims and a 6 yr 100,000 mile warranty? What kind of price should I offer for the car???
