I have been using Turo for a couple of weeks now as a driver. Depending on your location, you can rent a lot of vehicles you won't find at AVIS. There is a gorgeous, pristine 1961 Corvette for rent in my city, for example. It is disrupting the car rental market, but since car owners can set their own prices, do some shopping around before selecting your vehicle.
