This is a Fiat 500 Weinsberg Limousette, from 1959. It was a german only side-project, based on the ultra popular Fiat 500
In Italy many people used to think Germans lack style and sense of beauty (please take no offense, I'm just reporting a stupid popular belief!)
But Fiat 500 (which is a great car: it has been the first real popular car in Italy and it's considered a an artwork by Dante Giacosa, and it's featured at MOMA in New York) proved to be one of the most modified cars. Often with ugly results:
This is the 500 Jolly - ideal for people living in warm places. It actually has the back couch made of vines!
This is 600 Multipla Jolly - the same as 500 Jolly, but based on the ugliest car in the world: the original Fiat 600 Multipla (when a car is called Multipla, is always horrible)

Here's the original Multipla.
If you think that the sinergy between FIAT and FERRARI produced always great cars like the F-2002/2003GA or like the wonderful FIAT DINO

(this is the wonderful FIAT Dino, named after ENZO Ferrari's son)
just take a look at FERVES (that meand FERrari VEicoli Speciali: Ferrari's Special Vehicles). It actually is a sort of 4x4, that was also used as a rail-vehicle (it actually moved on rails, and it was used as a fast train-support in Italy)

.
By the way, going a little off-topic, don't forget the prototype of FIAT X1/9. The real car was really beautiful, you can see it here with the hard top
The prototype was the uglies car in the world: a strange sci-fi nightmare. It has never been produced. You can see it here
but somehow it has become Wonder Woman's car!!!! Just take a look at the model (which I own since my childhood)
It's a FIAT X1/9 prototype (and so it's written on its underbody), just look at the position of the lights!
