Can anyone recommend a good car hire option that we can drive around Italy for 2 weeks?
They are pretty much the same, if you stay way from the major players like Budget, Hertz etc they will be a bit cheaper. Just be careful of some of the hidden charges like where you pick up and drop off and a charge if they not the same.
Cars for anywhere, we call up Autoeurope, a broker working with reputable agencies. Go to the web site and find the toll free number. Otherwise get reviews on any company that is not a major one like Hertz, Avis, etc. And read this about driving:
