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.
