I'm going to disagree with basically everything everyone said.
If you want a Z in college: Go for it. That's what I did, and other than having to replace worn out tires and oil changes, it never was out of service for any length of time.
That being said, if you want to drive a Z, make sure you get one that you *know* runs, and runs well, and *don't* try to modify it until you have another DD.
