Racing games with track & championship editors?

Modnation Racers sounds like what you want, although it's more like a Mario Kart style with items/powerups and cartoony rather than realistic.

Thank you! I actually own Modnation Racers. I'm not sure if you can actually create a championship with a list of tracks in a specific order. Though the game itself doesn't seem to hook me. While I'm not looking specifically for something super realistic, I think the offroad games tend to draw me in more.
