Consider local car rental companies

When searching for a low price on your next car rental, price local companies as well as the majors. Avoiding the chains and renting through local agencies can save you money, particularly in touristy areas in Florida and California, where competition is stiff. The potential downsides include limited counter/office hours, infrequent shuttle service, limited car selection, and no guaranteed roadside assistance.
