Retro-futuristic concept from Frankfurt perhaps? No, this spaceframe-monocoque MPV, with independent suspension, coil springs, flexible seating and push-button doors, was built in the 1930s by a gent named Bill Stout.

Unfortunately it was about four times more expensive than comparable cars, so it’s been consigned to history, it’s innovations mostly forgotten.

(Thanks to kingdom hoop for the pointer.)
