To give you an idea, I drove my '82 GTV6 over a scale. It has no aircon parts and the car was empty. Quarter of a tank and my 85kg body and it was 1350kg. The 75 would be heavier.
That's pretty much what we had:FWIW, the 87 US version Milano owners manual lists the curb weight, with a full tank, as 1320kg (2907lbs) for both the 2.5 and 3.0 versions.
