I'm at like 92% and haven't complete one A Spec Endurance and almost half B Spec Endurance. It seems like you can 100% just completely the available events.
Hey guys! Why in such a hurry? Enjoy the game.. GT6 wont be out in atleast 4 years. Im just cruisin cars around various tracks to compare them to eachother.. I would hate to be 100% yet..
