Collectors and enthusiasts now have a new way to purchase the latest slot car bodies: Auto World's Freewheeling Chassis Option! The Freewheeling Chassis models have a NON-working "motor-less" chassis with only the chassis frame, wheels, tires and axles included. The bodies are the very same as the standard electric motorized X-Traction models, but come with a bare chassis at a special low price.The Freewheeling chassis does NOT include an armature, brushes, magnets, pickup shoes or springs, or a guide pin. Pop the body off the empty chassis to use on the X-Traction or X-Traction Ultra/G chassis you already own! Release 6 includes three ALL-NEW body castings! They are the Dodge Viper Competition Coupe (dark blue), 2004 Chevrolet Corvette C5R (yellow) and the 2006 Dodge Charger SRT8 (deep black). Also in this group is the all time favorite 1957 Chevy Nomad with wild white and red graphics, the '77 Pontiac Firebird in dark metallic red and the Jeep CJ-7 in dark green.
