Subject: Car rental in Italy

I guess it is time to start thinking about the trip to Italy next year to see the sights and lookup Cugini in my dad's hometown.

I am not sure what size car to rent. There will be two adults with one suitcase each and some type of carry-on bag. possible two bags for my wife. :) I don't want to overspend but, I am 6'2 tall and don't fit well into may small cars. We will be driving from Florence, down through central Italy and end up returning the car in Rome a few days before departing for home.

What size car, based upon Euorpean/Italian, standards should I request? Automatic or stick shift, does it make a difference?
