Credit Farming in Gran Turismo 5 (100,000 Credits in 5 Minutes!!!) [Read Description]

100,000 credits in 5 minutes in #granturismo5 . This method is (from my experience) the easiest way to earn quick money in the game and doesn’t require insane skill to perform. All you need is a 500,000 credit NASCAR and the American Championship race. To make this challenge easier I suggest changing the oil and upgrading and tuning the suspension, aero, and transmission in the NASCAR so that it handles better.
