Jo from the Fiat club has an early 1973 model, it was an ex Fiat car never sold to the public, and hers is a 73 build. Been away on hols, nice one chris getting that car. Sell the BIS mate, the aircooleds are appreciating in value and rarity and your FSM is very similar in appearance to a BIS anyway... if you sell the FSM I am sure sooner or later you will regret it.
