A couple of weeks ago there was what looked to be a vey Nice Silver 67S sunroof on E-bay; i believe it sold for around $30,000. The guy selling it said it was one of 18 producd for that year. i E-mailed him and questioned him on where he found out the info that only 18 67S Sunroofs were manufactured. His response, was that he had been restoring 911's and 356's for over 30 years. End of response; Is it possible this number correct? Seems awfully low to me; Anybody care to elaborate on this thread?
