Would be nice if we could repaint racing cars and remove the livery, though it still wouldn't look much like a road Diablo 👎
As for the Miura, probably my favourite car of all time but umm one of the rare occasions where PD don't seem to quite get the dimensions right. It's simply too "short".
Another classic example of this that lives on in GT5 is the Elise, more so the first series. The Elise has always looked sort of balanced from the side, as is the case with a lot of MR cars, with just the right amount of car front and back, but the older Elises in GT always looked, well, sort of fat and almost wedge-shaped, with a short back and long front, and too high. The balance is just a little wrong.
OK off topic now, maybe I will raise this as another thread, it always surprised me when they get the dimensions of a car a little wrong though...
