Love this! I'll always be crazy about Personal Luxury cars. I wish there were more available. I know there are some resin kits (which look great btw) but they are a bit too pricey for me. A great article on this class of cars was done a while back by Tim Boyd in Scale Auto.
Great build. A few of those shots look like something out of a Mannix episode. (P.S. Yes, I know there were probably no Demons in any episodes of Mannix, but it just has that vibe. That is a great Diorama.)
Beautiful Coupe deVille. A question - Was there ever a model kit of Jo-Han 1978 Coupe deVille or is this the promo? In all my years of collecting, I've only come across the model kit of the 1977 & 1979 Cadillac.
