National - Which Full & Mid Size should one pick

I have owned the new Malibu and loved it. I am going to be renting a national car either Midsized or Full Sized and would like to read the FT community comments on National's full sized and mid sized cars.

I will be hauling people (4 or them most likely) and I want to try something else out than the Malibu since I know how much I Love the Malibu. Would love to read some opinions about other cars in those classes of cars.

Malibu used to be Mid-Size car with National and very eay to get it. However, after enterprise take over, it is now considered as a Full-Size car.

Actually, it is a standard class. Just a step below full size.
