All-wheel drive grip doesn't have to break the bank. The Subaru Impreza starts at just over $24,000 so there's no need to skimp on Fido's food. The new RS model gets a sport-tuned suspension, unique interior and most importantly, a more powerful 2.5-liter 4-cylinder. Tom Voelk checks out a fully optioned model in Oasis Blue and finds it frisky and affordable fun, as long as you don't crave a manual transmission.
