In 1977, Dennis and Kyle Mecham turned out a limited series of grand touring Trans Ams that they dubbed the "Macho T/A". These cars were sold through their father's Pontiac dealership and moved unhaltingly out the door.
Due to the success of their pilot year, DKM Design, Performance, Inc. was formed in 1978 and the program was expanded to over 200 cars which were made available to other Pontiac Dealers. Another 200+ cars were rolled out during the 1979 model year while the Pontiac 400 engine was still in vogue.
