Yes, I've been running that, but the X1 cash trick makes it so that u don't have to grind urself and u can let the game run by itself so u can earn money without having to replaying the same course over and over.
Job done. It could use an oil change but that's about it. Hope it serves you well and if it keeps being passed on maybe it'll end up the highest mileage x1 in the world.
I have the same problem, so sick of grinding:S
I tried to get a X1 from the Vettel chalange, but honestly, im not good enough by far!
