All of those things annoy the heck out of me, too.
But some things that drive me nuts:
How when you buy a car for several million credits, drive it a little, and realize it's crap, and you go to sell it, and the game tells you that this particular car cannot be sold. Or, if you're lucky, the game will let you sell it, but the car is worth almost nothing, and you're losing out on several million credits. WTF? I mean, really, is there any reason the car cannot be sold, even for the drastically reduced price of most cars that you sell? No, there really isn't. And I don't really think that this feature is realistic, either. Chances are, in real life, if you bought a classic race car for several million dollars from an auction or a wealthy individual, the car has probably been bought and sold several times in its lifetime. But in Gran Turismo 5, apparently the car cannot be sold, physically. You just get the option to remove it from the garage, but who would want to do that? That's basically like purchasing an expensive computer, hating it, and then throwing it out the window. And that also brings me to the massive depreciation that hits cars immediately after you purchase them. Why? It's like the player has the curse or something, it's ridiculous. If you go to the used car dealership and purchase a Subaru Impreza for 27,000 credits, and you go back to sell it, it's probably only worth 6,000 credits, which is a bunch of bull. It's as if from the time that vehicle was purchased new by its original owner until the time you purchased it, the vehicle did not depreciate at all. Not one cent. And that itself is flawed because if I were to purchase a new Subaru Impreza from the new car dealership for, say, 35,000 credits, and I turned around and sold it, it would only be worth 7,000 credits or less. That's just crazy. How come the guy who purchased that Subaru Impreza that you bought from the used car dealership didn't experience any depreciation on his vehicle. My only theory is that, yes, he did experience the massive depreciation, and the used car dealership has an astronomical markup on its vehicles because they can. In that case, the used car dealership is a scam. Whew, glad I got that off of my chest. Thanks for listening.
