I have personally spoken with Fred from Tamiya about the Rakiri body. He told me it was 100% not a real car. Whatever it may appear to look like, I have to take his word for it being a fantasy body. Since it was not allowed at TCS last year for reasons of realism, I would have to assume Tamiya USA does not think it is a real car either.

I also have to reemphasize what Kevin has said about the PFM-10, MX-Stang, etc. These bodies are made to resemble real cars as much as they can without a lawsuit. It's pretty obvious what car they are modelling.
