Rome car rental

We arrange our cars by calling up the broker Autoeurope toll-free [others use the web site]; get zero- deductible collision. Read this about driving in Italy [and about ZTLs, limited traffic zones]; avoid leaving anything of value in a vehicle when parked [and have an IDP]:

While Autoeurope is convenient, that convenience comes with a price -30-40% more. I've used Sicily by Car with great results, and far cheaper than the big rental brokers. You can also check Kayak for easy comparisons.
