I love cars and have really been wanting to get one of the nascar games by ea. let me also say that I'm a huge fan of gran turismo, and its level of realism. I'd be getting the xbox version, and online play isn't a concern of mine. my real question, if anyone can answer it, is which would be better, the 2005 version without the team-based strategy, or 2007 with the teams and whatever other updates in quality they would've made?
