We bought Mario Andretti's sprint car stand from 3n1 race shop in NJ very cheap. We made one that can roll anywhere with a car on it for our own use. It makes things easy when clipping or repairing twisted cars because we can also use it to straighten them due to its integrity. A couple of lengths of square stock and scrap I-beams and anyone can make one. We have around $500 total invested. You can buy the steel at any local scrap yard for the price of weight.
