Well, at present the cars are pretty much written off at the end of the year as total losses anyway - you might see a few cropping up for sale, but for well below the manufacturing costs in my experience. So forcing a sale wouldn't really change the economics of the situation in the way you're thinking. Who would buy though? The cars gain new parts on a race-by-race basis - they're never line production vehicles so there'd never be a stock of parts available to support them. The support infrastructure to run them is horrendously intricate, components are designed to be inspected every few hundred miles.... I can't see how it'd be viable - the current market that buys the few cars that crop up is hardly enormous.
