Here is a new photo I found/purchased on ebay of CHP #E408445 (a 1985 SSP) -
This is the only silver & white SMPV (Specially Marked Patrol Vehicle) from the first year (1987) of the pilot program by the California Highway Patrol. To review, the CHP repainted five (5) SSP Mustangs that first year, along with Dodge Diplomats, Crown Victorias, and Chevy Celebrities (15 cars total) for the purpose of stealthy speed enforcement of truckers. This picture is different than the others I have seen, with the shot being closer to the car and at a slightly different angle. The original I received of this photo I more clear than the scanned copy I posted, and it shows one of the special low-profile Show-Off rear deck lights, as well as the relocated antenna on the decklid.
