Something that has aggravated me about this game pretty much ever since I started doing liveries was the bizarre system they have for car painting, and the confounding limits. At first, you could have 1000 cars and...500 liveries? I was running into problems within six months and had to delete a bunch of downloaded and saved liveries. Then they changed it so you could have 2000 cars and 1000 liveries, and six months after that I'm bumping up against the limits again. So if I want multiples of the same car (which I do, tuned up and painted in different ways and for different types of racing), at some point I'll end up with multiples that look exactly the same. I've never seen a car game that lets you choose car colors for only half your cars.
But also, it seems that the number of vinyls is somehow tied to your number of saved liveries. You know the "Failed to save" error you get when you have too many liveries? Delete a vinyl or two, suddenly you can save a whole new livery.
And now I'm running into problems with cars from the auction house that already have liveries applied...apparently those liveries count toward your limit as well. When you try to collect the car, guess what? Failed to save. No car for you, no nice livery for you.
They had to know that some of us would want to personalize every car in our garage, right? How do you make a game for car people and not realize they'll want to paint all their cars? We can tune all our cars, so what is keeping them from making it so you can have a livery for each car? Or as many liveries as your hard drive can hold, for that matter? If it's a space issue, let me allocate as much space toward liveries or vinyls or tunes as my system can handle!
