Alamo Rent-A-Car started in 1974 in Florida and has locations in the United States, Canada, Mexico, the Caribbean, Latin America, Asia and the Pacific Rim. In 2007, Alamo was bought by the Taylor Family of St. Louis, which also owns Enterprise Rent-A-Car. Alamo's policies allow underage drivers 21 to 24, but will assess a daily surcharge and will not rent certain specialty and larger vehicles. There are two states, New York and Michigan, that mandate rentals for 18-year-old drivers, but there is an additional charge added to the surcharge, and the total can be quite pricey.
Dollar Rent-A-Car provides cell phone and child safety seat rentals and facsimile and express car return services. The minimum driving age for Dollar cars is 21 years old at most locations in the United States and Canada, but only under certain circumstances as noted in local policies.
Thrifty is a worldwide car rental company and boasts over 300 rental locations in the United States. They offer a matching rate plus a 10% discount if a lower rate is offered at another company. They team with some airlines and hotels in giving frequent flier miles and hotel points. Thrifty policies do allow 21-year-old drivers at most locations, with specific information found under their terms and conditions. Again, extra charges apply to underage drivers.
