My husband and I will be renting a car in Venice and driving to a farmhouse southeast of Florence to stay for 5 days prior to dropping the car in Chiusi and taking the train to Rome. It's just the two of us, and we are only bringing 2 carryon suitcases and a day backpack. Should we get the two door fiat ($293 US dollars) or the 4 door Peugeot ($322 US dollars) from kemwell? Both have AC. Is the 2 door going to be too small? I'm 5'6" and small and my husband it 5'10" and a little stocky. Is it worth it to pay $30 more for the 4 door? Thoughts?
