Help me identify these old racers!!!

Who are these guys and what are these cars. does any one know exactly the make and model??

Ive done i little research and found that i think they are Bugatti's. but what year?? See the pics, the blue one is 1931 bugatti T54. the tail is exactly the same. But the hood and grille of the cars on the left are square (kinda like Mercedes) so i still need some help.

 

Don't look at the bodies, they've been crashed, bashed, updated, backdated and recreated.

Look at suspensions, wheels and engines to become an expert.

 

We had a couple of Threads already, and we did find out what they are.
