The first issue were fitted with hard to find knobbly grey plastic tyres but all later ones had knobbly or smooth black plastic tyres, Two issues can be found without trim to the grille which is also hard to find. The earlier issues were fitted with 1mm wide wheels but the later issues had 0.5mm wide wheels. The final issue in blue had a white dashboard which is rare.
The Bugatti was recoloured to red and this usually has a gold radiator grill but sometimes the trim is missing. It too had a brass plated steering wheel, roadwheels and handbrake. The dashboard is white plastic but the final issue had a black dashboard which is rare. Bugattis painted metallic green are believed to be pre production models and are very rare. The Bugatti was deleted in 1967 to make way for the 1913 Cadillac.
