They churned out tens of thousands Cameros in 3 years (67-69). Abeit many were 6cyl or base models, but any SS/RS or similar trim is collectable now. As will be any V8 hemi in the future. I feel lucky to have found a 67 no rust car with 87000 on the clock. If you can find a 80k mile v8 hemi in 40 years you will be looking at a sought after automobile. Demon and SS I think will be the most sought after, and certainly some SE's just due to their low production numbers. Then redeyes of any config just because they have the HO engine but any hellcat variant not driven into the ground will be desirable. Just like any Camero, Mustang, GT0 is today. Like previously said, they bring back memories.
