Since i don't know exact numbers of all different versions produced and imported i can't tell how much survived here in Holland, but i know lots and lots of Fiats from the 70's and early 80's have disappeared because of the nice wet weather here.
When i was running the, then only, 131 club in the 90's i noticed that there were not many Racings. Most members had a 1600 CL. Nowadays i think there are only a handful left.
Besides, and this makes me angry sometimes, the 131's have to make place for 124 spiders
