Doc's license plate "51HHMD", which stands for "1951 Hudson Hornet, M.D.", is missing on the toy itself. On the boot (trunk) lid of the car there is a bump in the metal sculpt that appears like an error. However, the Hornet "rocket" logo should appear on this area. This detail, together with the missing boot lid chrome pull was corrected for the decal applications on the Fabulous Hudson Hornet. The Red Wheels variant of this model, released in the 2008 3-pack, is also missing the "Dirt Track Racing" text on the tires, has the wrong wheel style, and should have been produced with a "dusty" paint finish like Dirt Track McQueen.
