I have an Edsel on my layout. It's a 2-door hardtop not a convertible, but the body size is the same. Anyway, my Edsel is a good fit to O-scale structures on my layout - refer to the attached pic of the car parked at Stella's Diner alongside other 1950s autos.
The Plasticville structures are a bit undersized for O-scale. IMHO, they are better suited to S-scale layouts with AF trains.
