This A-Series 911S is a long wheelbase car which topped the range in 1969, and was built by R Gruppe co-founder Cris Huergas and so can be considered as the club's poster child. The invitation-only 'hot rod' club focuses on the 1963-73, 0-Series through F-Series, air-cooled, 2- through 2.4-liter cars (in 1973 the Carrera RS carried the 2.7-liter motor and thus is the car to emulate).

Acquired by R Gruppe co-founder Cris Huergas of Alameda, California in May 1992, this 1969 911 S was sound but tired. Huergas then met 911 enthusiast Ernie Wilberg who gave him a copy of the factory Sports Purpose manual for modifying 911s to FIA Group 2 race specification. Huergas soon realized that he could modify his 911S this was so he sourced parts but left the 2.0-liter, high compression, 180 horsepower engine untouched. In August 1995 his Sports Purpose car debuted at Concorso Italiano and subsequently featured in the April 1998 issue of Excellence magazine. Freeman Thomas took a strong interest in the article and contacted Huergas about his own 1969 911 E. The two of them finally met at the Monterey Historics in August 1998, forming the R Gruppe in May 1999. The club has a 300 members limit even though it has the potential to grow much bigger.
