I think the biggest disappointment is the lack of custom parts for to many cars. For example, the Asterope body kind of looks the same as the Sultan, so why couldn't Rockstar share some of the custom bumpers from the Sultan? Other cars with potential like the Emperor, Picador, Surfer and even less likeable cars like the Dilettante should at least have a few custom parts to satisfy the players. The Stallion lacks parts as well, even if that car is supposed to be a good reason to upgrade from lg consoles.
Sultan mods on the Asterope? How far is your character in his mid life crisis, goddamn?
