According to Forbes, it is sometimes possible to buy concept cars. In June, 2002, Ford sold 51 concept cars in an auction, with the proceeds going to charity.
It is unusual but not unheard of for concept cars to be sold. Concept cars are not usually built to be driven; they are designed to showcase the ideas of car designers and engineers at car shows. Concept cars are often built without working parts and engines, and they are not designed to withstand the rigors of being on the road. Collectors buying concept cars are unlikely to try to make the cars roadworthy although it is possible in some cases to do so.
