Hi,
I believe you are mentioning the pre-release demo, with had some cars more in the Arcade Mode selection menu than the full release. In other hand, you can select any car in your garage.
Thanks very much for replying. We use the disk for the game, what is the pre-release demo?
There has never been more than about ?8 cars available in Arcade on the disk version.
However, if you look on the left hand side when you go to select a car, there is an option to load a car from your garage instead. Even if you haven't bought any cars in Brand Central, you are awarded cars for lots of things including doing 26.1 miles in a day, so there should be something there you can choose to drive instead.
Hope that helps!
And welcome to GT Sport
