Go make a single team (private not public). Go to preseason Rumble in NASCAR and run the 20-lap Richmond race 20 times for 400 laps total. That will get you 20 gold + at minimum, R$100,000. You will most likely get another payout when the competition ends of R$.

It doesn't get any easier than this. This is one of the cheaper cars and it only takes 1 minute to service. You don't have to win the race but you can earn extra R$ if you do of course.
