Hot Wheels: Mechanix

Hot Wheels: Mechanix is a racing game where you get to race with and customize your very own Hot Wheels cars. The primary objective of the game is to win all the races while collecting X-Tools to unlock new cars and customize them to make them better with such things as wings, mud tires and bigger engines.

Initially there are three stages available, but as you play you can unlock four more, making it seven in total. There are also 18 different cars (you start out with six, but you unlock more as you win the races in the game).
