This is the car coming home from Ohio on the trailer. I traded my low mile 1997 30th Anniversary Camaro Z28 for it. The Cutlass SX Package is defined as: "the Y-79 Performance Package and the car was named the Cutlass Supreme SX. The SX featured several 455ci engine options, a 400 Turbo Hydra-matic transmission, a cut out rear bumper showcasing the dual exhaust, and other goodies not found on a standard Cutlass Supreme. Sophisticated styling, luxury options and great performance create the ultimate gentleman's muscle car!"---Thanks to sx455.com for the information!
