This is new. As it’s just happened, this is the first time we see this car, and probably a long time will pass before we’ll see another one for sale.
It’s called Neckar/Fiat 500 Limousette, built by Weinsberg coachworks between 1959 and 1963. Weinsberg also built the Coupé version on the same Fiat 500 N platform; this last model is even rarer than the limousette. Both models had the ragtop and descending glasses on the doors.
This particular car has basically no description but it’s clear that it is a survivor, everything is in place including the precious side and front aluminium trims. Interiors is stock (the same of the Fiat 500), as well as the engine which is probably the original one. This car is not a beauty queen but it’s as rare as funny to stare at. Find it for sale at £5,490 (today $8,300) here in Czech Republic.
