I was wondering what the optimal setup for an autocross car would be. I know this is a very vague question, but it's interesting to talk about the different possibilities. To be specific, I'm wondering about cars that would run a tight course without much modification (probably a "low level" class such as stock), and also serve as a daily driver.

In my mind, the optimal car would be a LIGHT car, with a sporty suspension and sticky tires (prefferably a cheaper car, too). If anybody could add to the list, or propose other ideas, this could be a great discussion.

On a side note, how would this do:
