Vehicle selection
There are cars that should be simple to use but can affect the difficulty that you'll be in. If you are a beginner, you should choose "Supermini" since it's the only car you can use but if you're tough, you can take a "Sports Coupe" which is on medium difficulty. The car you choose will affect all the modes involving computers. Cars you unlock after beating Face Off.
