Smadman...just read these postings. I'm a RGruppe fan now. I'm retro modifying my "old" 88 Carrera to a 73 RS look with a ROW 3.6 motor. S's are fun to drive, but after 18 years and now with "owiginal" rhetoric that you see in these postings it's someone elses turn for my car. Just fielding the emails and phone calls are time consumming. I've had people from literally ALL over the world email me about my car. The questions are not few. Some have lists of 20-30 ?'s. I have a business to run. If the chassis and motor #'s match, and there is no need for paint,interior, and motor rebuild what else is there to decide ??
