How do you know it wasn't a genuine Impala SS? Anyway, on a recent vacation, I saw somebody driving down the road with a souped-up 1930's coupe of some kind and a matching trailer smaller than a teardrop trailer. I also saw a BMW Motorcycle that had the rear end of a BMW car of some kind. I wish I had some pictures of them.



With those taillights, it's a 1968. Anyway, I'm glad you explained downsizing to CCF. It fits in so well to what I was talking about here:
