Select Single Player and make a Custom Race on the Michelin Test Track Oval. Give yourself 3 laps just to be on the safe side and make sure you set it to 7 AI players! Give yourself an Enzo Ferrari and give the others Austin Mini Coopers (set them to Steel difficulty too).
This will be fairly easy because of obvious reasons, you're five times faster than your opponents, giving you the opportunity to scrape all of them!
