Unlike common cars, the Slingshot's gas cap isn't hidden away under a fuel door. Instead it is proudly displayed atop its rear body. It seems prudent then to make this facet of the Slingshot as handsome as possible. With Slingmods' wide selection of colors and variant styles, this is not a hard task to accomplish. Drivers have an entire inventory from which to select their favored brand and color, so that every Slingshot can be matched with a crown that denotes its true value.
