The "California 500 Special" is a version of 1969 AMXs that was sold only by members of the Southern California American Motors Dealer Association. It was part of a marketing campaign to commemorate the 1969 season at the Riverside International Raceway.[59] They would serve as pace car and the dealers would sell replicas.[60] All were finished in Big Bad Green with black stripes and included the 390 Go-Pac, automatic transmission, air conditioning, power steering, adjustable steering wheel, tinted windows, radio, light group, visibility group, and a saddle leather interior.[60] The cars also featured "Trendsetter Sidewinder" exhaust side pipes in place of the molding strips on the rocker panels and were identified by brass plaques mounted on the hood blisters that had crossed checkered racing flags and the words 500 Special.[3] A total of 283 AMXs were built in Big Bad Green for the 1969 model year; however, the exact number of California 500 Special versions is unknown with only an estimate of 32.[61][59]
