is it an Austin Allegro 3
I can’t believe they thought that was an improvement over the original design.
You have a point there. The orginal was nicer. Here is my Selection
Fairly easy if youve seen this car before as its one i actually own.
Chevrolet Corvan/Greenbrier?
Nope
fiat of any variety? like a 131 maybe
IIRC it was a matter of fitting an existing design into a new body, and the nice one was too tight, so they inflated it “a little”…
It isnt Fiat or an intalian car of any variety but it was designed by an italian styling house
Triumph Vitesse?
Yep! Specifically My Triumph vitesse 6 from '64
Nissan Pulsar/Datsun Cherry?
Saab 98
At first I was like “I’ve seen this car, I have no idea what car is it, but I know I’ve seen it” 
But then it clicked, aha, some old Saab probably. Well, being a Saab fan made it easier 
Mercedes-Benz CLK GTR?
No
The current Alpine A110?
Nope. Hint: FWD
