I can't really disagree with those who say that the standard cars look quite bad - they really do. The problem is that by removing standard cars, many, many iconic cars will disappear... Cars like the Zonda C12, C1 Corvette, 22B Impreza, Mk IV Supra, LMP cars like the Audi R8 and Toyota GT-One, the FGT will disappear too... Not counting all the Group B and Group A rally cars. We wouldn't have RUF cars either...
You get my point: the solution is
not to remove all standard cars. What PD really should do is simply upgrade more and more of them to premium and semi-premium, like they did for GT6, while
leaving the bad looking ones still in the game.
Gran Turismo is about the car culture and history. I don't want GT7 not to have something as important as an Audi R8 or Lancia Delta S4. Even if the Delta S4 doesn't get premium or semi-premium treatment for GT7, I still want it in the game. Same with all the other iconic cars.
