We usually sell them before they’re junk. But my son converted an old shifter chassis into a bomb proof yard kart, with a Honda 4 stoke on it. Can’t break a racing chassis in the back yard!! I almost feel sorry for it, but it does NOT break—and you can get parts for it!
The Play Station/IRacing seat idea has some merit. But even a bare frame isn’t light or easy to store. I think some of the purpose built game chairs might be a better buy, AND they’re all ready to go.
