Pontiac G3: Compared to the first four entries on this list, the G3 is positively loaded with standard equipment. Air conditioning, a six-speaker audio system with CD player and auxiliary input jack, and a tilt steering wheel are all standard. A 106-horsepower, 1.6-liter four-cylinder engine mated with a five-speed manual transmission earns it an EPA rating of 27 mpg city/34 mpg highway.
