This is a completed plastic or resin display car model.
From the manga and anime "Shakotan Boogie." Part of Kyosho's Mini-Z Auto Scale Collection line of body sets, this painted and pre-built body, including tires, wheels and a display chassis, is beautifully detailed and attached to a base inside a clear plastic protective case---but it can be removed quite easily and fixed to a Mini-Z R/C chassis (for MR-01/MR-015RM chassis sets) for racing purposes!
