Die cast variations: (2005) ▪ Glossy black body with green markings, 6 spokes ▪ Flat black body with green markings, 6 spokes ▪ Silver body with green markings, 6 spokes ▪ Duracell variation - Silver body with regualr wheels, ''Duracell'' printed just behind the cockpit (very rare - never made it into full production)
Note: If you examine the silver RD-03 next to a true ZAMAC vehicle (see picture below), you'll see that the RD-03 is actually painted a ''sparkly'' silver color. A true ZAMAC variation would be more ''flat.''
It?s rumored that the silver version is a Toys-R-Us exclusive but it can be found at other retailers.
