The best person to ask would be Vin, as he is into his fiat camper vans and seems to know the revisions etc as your original thread you posted in december 06 shows
The Fiat Fiesta was an 850cc small campervan with a rear engine and ingeniously fitted out inside to maximise all the internal space usage. It was only called the Fiat Fiesta for a short time and was superceded by the Fiat Fargo which had a few design glitches leading to condensation and leakage from the extending roof area. It slept 3 people inside two on a double bed and one in a bunk bed in the extended roof area. A specially designed tent fixed over the rear door adding a roomy area for another two camp beds. It took two star petrol but where this was unavailable in remote areas it could be topped up with 3 star with little problem. The boot area could be extended with a fold out floor and side panels that came with it.
