whats it worth 65 formula s 4 speed

I like the tach, but other than that anything more than 500.00 is a stretch, the bodies prob junk, looks like someone cut the quarters for bigger wheels, and there not worth much money mint. I hate to put the cars down because I love them and even own one. There's a guy on craigslist in Detroit selling one for 2500.00 in pretty good shape that you could drive .
