There are at least three different versions of the Fiat:
1. One with hood scoop seen in the first post.
2. One with hood scoop and side vents seen in the pictures above.
3. One without either hood scoop or side vents seen in post number 23. This car is referred to as a Coupé Monza on another forum and it is also have a sleeker and more well-proportioned design.
Then of course there is also the very similar looking Alfa shown above.
