I just got it today and you need 45 wins to keep it. With all this damn math HW probably won't get all the wins today. Probably take me 3 days by myself but I got 7 days so I'm not worried. All help is appreciated tho.
I WAS saving my blue points to buy the cars that you could only buy with blue point. But since they got rid of that only blue coins non-sense,and all cars are now purchasable by both gold or blue. I probably use them for the last engine upgrade.
