Pontiac Vibe: Fraternal twin to the Toyota Matrix, the Vibe in its base form is fairly Spartan. It does come with a four-speaker audio system with CD player and auxiliary input jack, and a tilt/telescoping steering wheel. Power arrives via a 132-horsepower, 1.8-liter four-cylinder engine. Fuel economy is acceptable, with an EPA rating of 26 mpg city and 28 mpg highway.
