At that sort of price, well worth a punt! They are very versatile vehicles. In Italy they were used as taxis. My parents had one many years ago, and as secretary to the "Met Police Motor Club" Fiat asked him to help them get them allowed to be used as taxis in the UK, but sadly to no avail.
Although this version is listed as having the original 600 engine, don't forget, the 850 (and therefore 903cc) engine can be fitted, which gives a fair performance enhancement---all you have to do is run the 850/903 engine backwards (not difficult).
Abarth used the vehicles as "servicio" vehicles, complete with Abarth enhancements---painted as a Servicio vehicle, with a tuned engine, front discs and the engine cover raised, you would have a real cracker of a vehicle.
