I just finished a carshape for the Le Mans 1999 race. It includes one open (BMW, Courage) and one closed (Toyota, Mercedes) car. I tried to find some new solutions and also did. Sadly I was not able to fix the known bugs, but I think it's a good carshape.
Now the already existing cars (made by Chris Rimmer) need to get wheels and some other updates.
Some cars, especially the open prototypes, do not exist yet. It will take some time to paint them.
I'll put the carshape online after some smaller updates (so it will happen soon).
Based on this carshape we can make cars like the Bentley, the Audis, Porsche, Mercedes, Nissan, McLaren...
And I agree with you Chico Landi, we need those cars!
Do you want to make some??
