Owning a car can be a burden: paying for insurance, paying for gas, paying for a car-sitter every time you go for a hike. That's why Enterprise Rent-A-Car started CarShare, a community program that lets members take out vehicles around the city without worrying about any of those inconveniences. Once at the CarShare location, customers need only to use their membership card to unlock the door. Members can reserve a car by the hour—as well as daily or overnight—and low rates include the cost of fuel, insurance, and up to 185 miles per day. They enjoy a wide range of choices, too: electric and hybrid rides, SUVs and pickups, and passenger vehicles populate the company's stable of fuel-efficient vehicles.
