I am looking to purchase a 1982 911 Targa, it has a Carrera emblem on it, the seller claims it was imported from thailand, US records only go back to 4/17/91 when it passed the California emission inspection in Palmdale. Vin is wpoea0910cs161553, engine number is 930-106-102 OR. I seems to be a 3.0 normally aspirated SC. What is it?
