This is an official Convertible Trans Am. As you can see, it was originally silver in color and we transformed it to a black on black on black.  Rims were redone and interior was redone.  History says that in 1979, 1980, and 1981, GM sent 500 of these cars total to National Coach. National Coach cut off the roof and reinforced the frame and put on the convertible top.  The official cars have a brass plate in the driver’s door frame that says it was done by National Coach and what number it wasthis car is number 13.  Truly a rare and valuable car.
