Racing Rivals is my favorite racing game in the world. You can customize your car with spoilers, cool rims, side skirts, front bumpers, rear bumpers, and more! You can upgrade your car to make it faster, and race in multiplayer. I recently finished 5 out of 6 tiers: Los Angeles, Sydney, Tokyo, London, Rio. I am currently racing in New York. My current car for the tier is a 2008 Mazda Furai. To race in each tier, you are given a car. The choices for the cars depends. Or you can buy one from the showroom. Upgrading your car and customizing is the fun part. The Mazda Furai was a exclusive. Very few people have it, and it is one of the fastest cars in the game. Multiplayer is available, and the fun part is that your opponent doesn't know what's under your hood, and you don't know theirs. Contests are also a fun part.
