I'm aware. He can still read this thread and other people can try to use the same argument.
I don't see any reason to make it hard to get. You should be able to enjoy the car whenever. Even with GT5's simple lobbies, it was easy to make it so that you would never see the car online. Hopefully GT6 improves things further, so the people who don't like it don't have much to complain about.
Making it hard to get also creates another annoying problem, you won't find other X1's to race against. Ideally, you would want as many X1's available as possible so that races don't have to consist of 2-3 cars only.
