The 1969 Chevrolet Camaro RS/SS is one of the most optioned configurations of the first-generation car and also one of the most common subjects of misrepresentation.

The RS package was a visual package — hidden headlamps, special taillights, RS badging. The SS was a performance package — stiffer suspension, specific engine options, SS badging. They could be ordered together or separately, and the Z/28 was a separate package that could also be combined with either.

A genuine RS/SS should have both the RS and SS trim codes on the build sheet or trim tag. The combination is common enough that it's not rare, but the documentation should exist. A car wearing both RS and SS badges without documentation is potentially a non-SS RS with added badges.
