(Edit sorry about the title I cant change that.) Lets say you want the NASA shuttle which is 15,000,000 dollars. These are how many races to buy one car.(Without Gold BOARS? oh wait I mean gold membership.)
5th place:8523 races
4th place:8021 races
3rd place:7575 races
2nd place:7177 races
1st place:6,818 races
I would say go on a tean and get the money that way so its easier.
EDIT: This is just for base payouts.
(Sorry i did not mean to be a rant)
