Personal Opinion:
I mean, just LOOK at the Lambo; tell me it doesn't look like it would kick ass if it had proper racing specs. I think it looks awesome, and it gets going super quick, but I always found its handling to be rather bothersome. I think the car just NEEDS a racing version; It would most likely be a Gr. 1, where it would represent Lamborghini since it doesn't have any Gr. 1 cars as of yet.
Also, in case you're wondering: No, the Ferrari VGT actually isn't a race car; it's considered a road car. Funny, considering it looks and handles much like a race car.
