The car bodies are typically a hand-built steel body, however teams may also use a one-piece composite body. The composite body is a "common" item that may be run as any manufacturer branded car (i.e. only one style of composite body for all four car manufacturers Chevy, Dodge, Toyota). Teams then "brand" the composite body by the grill opening, quarter window openings and the vehicle decal package (head lights, tail lights, etc.). Due to the introduction of the Car of Tomorrow in the NASCAR Sprint Cup Series, many of the vehicles on the series are old Sprint Cup cars. Another popular way to get a complete body is to buy a "cut-off" body from a Nationwide series team and mount it on a chassis.
