Giannini did in 1972 the Giannini 132 2000 based on the 132 1800. I have a list with details and options in the big book about Giannini.
A little about the engine, indeed 1936 cm3, compression 9,5:1, 115 DIN horsepower at 7000revs, topspeed 180. They did a lot more interesting things on Fiats. As far as I can see since 1979 they ALSO personalised cars, including 131s( based on all models) and also the 132 all versions. What it meant as the book tells:
Emblems Giannini in the heart of the wheels
Leather steering wheel withGiannini heart for claxon
Right side mirror
2 big Giannini emblems, 2 Giannini signs for the windows(?)
1 big Giannini shield
3 small Giannini shields
Options: Radio, Alloy wheels, fog lights.
Stunning isn't it
, so I can change a car quite easily when I buy emblems in Padova
So, indeed there is a big difference between the "original"Giannini 132 2000 and the later personalised cars!
