This car looks has few misterious points which really puzzle us, it would be nice to solve them.
First, this car is claimed as a Veloce: we didn’t know about 750E cars made in 1958, but the car could even having been registered in that year. The chassis number plate is coherent with such statement and, watching the engine bay, the engine looks correct as well. The Weber DC03 are the correct carburetors without the choke system: also the head looks correct. There’s no photo of the engine numbers though.
This car should be a Veloce but we don’t see perspex door windows, the aluminium front bumper (the bonnet is made of aluminium) and neither the interiors trims, especially the door panels, which seem to come from a normal Giulietta Sprint. Last but not least, the asking price of this car is said to be “from” £9999 (today $17,000). Find it for sale somewhere in Spain.
