Can I contribute with some European stuff?
Alfa romeo Arna (built in joint venture with Nissan (ARNA: Alfa Romeo Nissan Auto) she has a Nissan frame and Alfa engine)
Volkswagen Pescaccia, a civil reproduction of a WW2 German army car (made on Beetle chassis and engine)
Citroen CX Wagon, like NONE of this cars were buyed by normal people: all of them became ambulance or hearse.
Audi A2, weirdest Audi ever built. This cas even has NOT a real hood: it is sealed and only a mechanic can remove it. The fake grille opens to reach the water, oil and wiper water caps, that's all.
BMW Isetta: a former model from italian car maker Iso Rivolta, the buiding license was buyed by BMW to build a cheap car to motorize the post-war Germany. The single front door remember a fridge and I think it's not so safe in a crash...
Delfino Feroce, a ugly method to use spare Subaru Impreza engine and mechanics... It's a british car, the good news are that the maker didn't have done another car except the prototype
(ah, the name is italian and means Ferocious Dolphin
Ford Ka MK1: a wheeled tin bubble with unexpected good handling and a "vintage" pushrod 1.2 engine from 80's Fiesta.
Renault 8: no, a falling pole hasn't hitted the hood, it's STYLE...
MATRA Simca Bagheera, a "sport" car with 3 (yes, THREE) front seats, mid engine and useless front hood. The trunk was over the engine, very useful if you plan to make a picnic and want to eat warm sandwiches
NSU Printz: another birth of the german art of making cars, in Italy we called it "the soap bar" for obvious reason... sport versions have unexpected engines, I4 1.0 litres capable of 70 and 90hp...
And that's all for now
