These days with the internet you can search far and wide for specific vehicles. eBay motors is one place to start. The few times I have looked there I was surprised to find true rare exotics for sale like Ferrari F50s. For your 1996 camaro I got 14 hits on eBay. Good Luck
I agree that cars can be found, but Camaros are problematic due to the demographic that buy them and trash them. I do not find many with the care, documentation,and miles that mine had. Not to mention expensive mods.
