A mid-pack racer in this league can almost assuredly dominate anywhere else. Someone could get a really good deal if they understand that; but if someone here is looking to improve their position in the ranking, I'm not sure a mid-pack racer has much of a chance at selling a car.
From my perspective, getting closer to a mid-pack racer, I would no long er consider buying a car, any car, but I've made handsome offers in buying a single wheel and axle, for research purposes.
Don't sell yourself short - you're pretty fast (I'm trying to catch you myself). I think you could sell some cars, if you can make them pretty and find the right audience. You might try eBay...
