I think it's a bit different from what I can see. Someone correct me if i'm wrong pls. Previously you have to buy everything. Then do the tunes from stage 1-4 and weight reduction. Now I find that You don't need to buy everything individually. Tyres were already available. Only thing you pay for is Tunes and Weight reduction. The transmissions etc are all there already. You can set it to auto setting or you can go in and change all the settings manually. Things like Gear ratios etc. But you use miles to buy the Tunes and Weight reduction it seems. The money is for buying cars only it seems.
