Used 2009 Toyota Prius Standard Hatchback 4D

If you’re concerned about the environment, this car produces minimal greenhouse emissions in stop-and-go driving. Speeds below 30 miles per hour are handled by the electric motor – the gasoline engine comes on only when you need more power or are driving at highway speeds. Nothing says "I’m Green" like a 2009 Toyota Prius parked in your driveway.

If saving money is as important as saving the planet, you can buy a Toyota Corolla for a lot less money and still get pretty good fuel economy and low emissions. The Prius’ long-term ownership costs are an unknown, as is the life of the battery pack and the cost to replace it.
