Robbins' cars were built and maintained by Cotton Owens. They were painted two-toned magenta and chartreuse, usually carrying car number 42 (though 6, 22, and 777 were also used). Over the years, he ran a few makes and models (Plymouths, Dodges or Fords) before buying a 1972-bodied Dodge Charger from Owens. Robbins had a few major wrecks during the 1970s, and he had Owens rebuild the car to update the sheet metal to the 1973–1974 Charger specifications, and then finally 1978 Dodge Magnum sheet metal, which he raced until the end of 1980. Robbins' final NASCAR race car was a 1981 Buick Regal that he rented and drove in a few races in 1981 and 1982.
