I had thought that as an older example of American Iron, the Cobra might be included in the ALS/500. For some reason DD doesn't like it too much. It might not be good for competition with its light weight and ungodly torque, so he may have a darned good reason. For our project I think one of the major complications is keeping the field of cars to a manageable size. That's why I haven't suggested any older cars. I love the Cobra, but I think it we lose focus by broadening the car selection to include the older stuff.
The Series One might not be a bad choice at all. I haven't picked one up yet because I don't play the single player game and they go for big $$$ on the AHouse.
I still don't see what the big deal is about big-wheelin on the Enzo. Did you have to use the lowest brand of race tire and skip all the platform mods to pull off a 998 or what? If we choose any other Ferrari, it should be one of their flagship cars, such as the F40 or F50. The F430 is fast, but it's just not a 'flagship' car. That's the same reason I prefer the Carrera GT over the 911 or Cayman. Both the 911 and Cayman are faster than the Carrera GT in game, but they aren't what you'd point to as Porsche's 'flagship'. Same thing with the Mustang vs the Ford GT. They're both fast, but only one is truly 'super'.
My current 'short list'
->no more than 1 car per manufacturer
