Its an F10 Sports Proto. It is Super Ten size (Between 1/10 & 1/8) This was the full body version of the same chassis for the F1 car called the F10.
The car is rare and parts are even more rare. There was even an electric version of this car with a Panoz body. (Extremely rare because the electric was Japan only)
Go easy on it if you want to run it for fun. If you want something for bashing, get something else.
