1975 911 price question
 

Hi. I'm new to the forum. Although a car enthusiast (primarly classic mopars), I know very little about Porsches. My son is considering buying the car described below. Please offer me any information as to what a fair price for this car would be. Also, my belief is that this car would be a fun and competitive car to autocross. Any info. about it autocross capabilities would also be appreciated.
Thanks, Rich
