They don't even look as good as they did in GT4 from what iv seen so far.
Unless PD has gone in to really make their cars look WORSE, I somehow doubt that. As far as I have seen ( mind you the full grid of standards, not the two closeups everyone is bashing, of One car, out of perhaps 799 who look alot better ). There is bound to be a bad apple,when there is that amount of number involved. It's no easy task to make those even compatible with all the new gadgets that has been introduced with GT5.
Wait for launch, judge with skeptical eyes if you must, but most people will probly not notice standard cars the first time they come across them, unless you prefer staying up in peoples bumpers heavily 💡
