Not very hamb-friendly..but anyone know what this is ? I have the "standard catalog of american cars" which has quite a lot of dream/concept cars from '46-'75 ,but its not in it.. Any ideas ?
If you held a gun to my head and yelled "Guess!" I'd say a prototype photo for the up-coming '68 Stingray, circa '65, before the long front/short rear was adopted!
It's the Dodge Challenger "Diamante'" concept car. It was several different colors over the years including pearl white as shown in your skectch. It has been restored and is in a private collection.
