Oh man it's been at least 15 years since I saw this cars....

Car in pictures 1 & 3 are Fiat 500s A.K.A. Topolinos
Those cars where fast on the road course back in the day, welded rims were a must and re-worked fenders to fit the wide race tires make the car look awesome, a full size go-kart.

and the one on picture 6 & 7 are Renult 4 I never could drive one of those... the freaking shifter comes straight out of the dashboard LOL
