What're rental car prices like? As much as I love driving my car, if it's major distance I kind of enjoy the fact I could call the rental car place if my car breaks down and they would bring me another car. That and I guess I depend on my car a lot and would hate for anything to happen to it.

That all being said, I did a 400 mile round trip a couple of weeks ago. My car LOVED it!!! I got incredible mileage and it was peaceful, in a driving kind of way.

I'd say go for it. And ditto on letting someone know where you are. Do you have Auto Club or anything like that?
