ive never seen a COPO or real shelby ever, but i know that there is a show (im pretty sure on the west coast) that is just for COPO's, Yenko's and the like. I saw it on TV once (My Classic Car). Real nice show, talk about sleepers. As far as comparing the two, they are both hella expensive for the real thing, ive seen original cobras at that auction they show on TV (forgot the name) go for more than 150,000. i think that would be considered a good deal. same thing for the COPO's though. can you imagine buying one as a kid for what, 7, 8 grand? and still having it now? talk about a good investment!
