New here and a novice so I need help and fast, car goes to auction Friday. Brothers car, I'm helping (thrown into this, doing all the work). He is 3rd owner, 29,000 miles. Awesome looking (silver/burgundy) and runs great. Problem is car is not all stock. Previous owner installed dp body work and maybe engine modifications( bigger inter cooler?) See pics)not a real dp car. Trying to contact previous owner but no luck. Engine #s appear to match. I'm guessing drivetrain#s match also but not sure. Any idea how to find out how many 930s were built with this color combo? Mecum requires engine casting #s, engine casting dates,engine assembly codes, and engine and vin/serial derivatives to be called matching#s car. Does that affect the price that much? What kind of reserve should we put on this ?
