Depend on the definition of working order. I have cars that run and drive but all need work to become race cars. Are you looking to build a race car or buy one ready to race?
I do have a take out cage for sale, one 4 door for parts an one 2 door that can be combined with the cage to make a new race car. I also have engines. I don't have any transmissions other than automatics that I am sure no one wants.
