I've now won gold in half of the enduro races, including racing through the Super Speedway over a dozen times, and have yet to walk away with an F1... I'm 74% complete (mainly missing a few series in Pro and most of Arcade mode), and my buddy got one at only 40% done. He thrashes my garage head to head because of that one F090 from the Speedway enduro. Any advice, or just more patience?
