Nissan Versa Say hello to the Nissan Versa. Starting at twelve grand, this puppy gets 38 miles to the gallon and replaces the Sentra as Nissan's most affordable ride. The hatchback model will be available this summer. Definitely not the best-looking car, but the gas mileage is impressive, considering it has a 1.8 liter engine (same as the Sentra).
