The R-Gruppe is an elite group of early 911 enthusiasts. They are all very passionate about their porsches. My father-in-law is friends with many of the R-Gruppies and see’s them almost weekly at Cars & Coffee in Irvine, CA. If you’ve never been to Cars & Coffee there, I highly suggest it. Great place to take kids for an early Saturday morning activity and check out some sweet rides of all types. You’ll see the R-Gruppe guys near the front of the lot with all of their “R-Gruppe” rides parked side-by-side.
