Why don't you play around with the free version, once you get to 100 events limit, purchase the licensed version. I did that. Also by the time you hit 100 events you will have gained insight into the workings of the software.
What plinkie link says - lol, is you are going to build components. You need to build the timer, you need to build the cars movement, you are going to need to build track(s) and all the wonderful things that make a game work (the background stuff is never simple, even for a simple game) BUT, C2 makes it easy, and a lot of fun. I catch myself trying to come up with different ways of handling a situation within the game.
Oh, I believe there is a car racing template to get you started. I haven't built car racing, but it is very doable.
Edit: Yip, C2 has example of simple car movement. New and select examples, templates etc etc.
