The feature was revealed during an interview at the conference. Kazunori pushed the fact that he wanted the player to feel like they actually owned the car, that it wasn't just a car in a game, which led to the feature. "Whether it be from PSP to GT5, to even future renditions, GT6 and on, you can carry over the cars as YOUR cars, as something you own, even if the system changes, you can keep it."
