The car is a Cadillac, but not a fancy one, with luxurious interior and and tons of chrome... The one I want to replicate is the one raced a the 24Hr of Le Mans in 1950... The one the french press called "Le Monstre" because of it unusual shape...
After 30 years two American cars went back to Le Mans. This time two 1950 Cadillac, one a pretty much stock Serie 61 (changed carburetors, add an auxiliary tank, and few other things), the second one built bi Cunningham with the help of the Grumman Aircraft, had a 5 carburetor set up and a more "aerodynamic" shape.
The Serie 61 was driven by Sam and Miles Collier, and finished 10th. Le Monstre was driven by Cunningham and Phil Walters, and finished 11th... They say because he spend over 30 minutes on a sand hole and had to borrow a shovel from a spectator because he did not have one in the car.
Here both cars.
Here the chassis/interior, the chassis is from my model parts box and it has dimension correct for what I think I'm building.
