A viewer suggested this car for the Sardegna World Touring Car 800, which rewards you with $727,500 credits per win with the Clean Race Bonus added.

How could I resist?

EDIT: Some people seem to have a problem with the word Glitch in the title. The "Glitch" in this event is to set your game difficulty to Easy to ensure you get the Clean Race bonus. You can get penalties without losing the bonus. You can even cross the pit line, knock the AI around a bit, and you don't lose your bonus. Technically, that's a glitch. But I've changed the title slightly so people won't be confused if they don't read this description.
