The gold cars, pictured below, also came with two interior colors, red and gray. Both sets had "Real Wheels" on DU-2 rims and SPEED RACER lettering on tires except the Assassin, which had gray-white wheels. The gold card Mach 5 was also released with accessories (saw blades and auto jacks). The accessories did not match the interior colors.
