Your clients will think your car’s a gas, even though you’ll hardly be using any. EV Rental Cars, specializing in environmentally friendly transportation, has just expanded its locations on the East Coast to include Baltimore, Dulles, and Reagan National airports, as well as Union Station in D.C. Add these to existing outlets in California, Arizona, and Pennsylvania, plus the backing of Budget Rent A Car, and you’ve got one promising company. More locations, including Dallas/Fort Worth airport, are on the way. EV Rentals offers a range of eco-conscious cars, including General Motors EV1 (electric), Honda Civic GX (natural gas), and Toyota Prius (hybrid). And the cars don’t just save you fuel and cash. They can save you time, since they’re often eligible for the carpool lane, even when you’re driving alone. (877) 387-3682,
