Do you remember the Davis Divan? That’s okay — neither does anyone else. "Produced" from 1947 to 1949, the Davis was one of many crazy post-war designs intended to feed America’s massively expanding automotive marketplace. Like many others, it relied heavily on war-era engineering and aircraft styling. Unlike most others, though, it had three wheels, seated four abreast on a huge bench seat, and its creator ultimately went to prison for fraud.
