Dodge Challenger Diamante.
This car took a few turns along the way to becoming the Diamante. The first 1970 Dodge Challenger convertible was pulled off the assembly line in 1969, and Syntex in Dearborn, MI, was tapped by Dodge to modify it into a supposed Corvette competitor (ala AMC's AMX) called the Dodge Yellow Jacket (First pic).
Not long after the Challenger had become a common site on the road (almost 77,000 were sold in its first model year), Dodge went to Syntex again, who modified the Yellow Jacket with a different nose, pared off a couple of taillight lenses, and replaced the shaker hood with a smoother panel, and dubbed it the Diamante, which was painted white with crushed diamond dust - or so the story goes (the puzzle pic). After 3 years on the show circuit, the car was badly scratched, and was sent to Creative Customs in Detroit, who painted the car a candied Tangerine Orange , (second and third pics). During Chrysler's money problems in 1979-80, the car was sold and resold. The current owner, Steve Juliano, had the car returned to the original white color.
