If you're looking for a good used car that gets great gas mileage, you've probably shopped for what conventional wisdom says is the "best" on the market: Honda and Toyota.

When buying used, it's hard to go wrong with a Honda or Toyota. However, the downside is that those cars tend to be at the high end of the price ranges for their classes.

So what's a bargain hunter to do?

Looking deeper into the market, you'll find cars that are overlooked gems. These bargains have good reliability records, offer space and value for the money, and get at least 20 miles per gallon and as much as 36 mpg, according to federal government ratings.

To help the bargain shopper, here are some vehicles we think are worth a look. These were chosen because of their relatively affordable prices -- all but one can be bought for less than $10,000 -- and their ready availability.

They are mostly conventional sedans that rely on the tried-and-true way to improve gas mileage: a small engine in a relatively lightweight chassis.

The Pontiac Vibe made the list because it's the twin to the Toyota Matrix, but costs as much as $1,000 less because it carries the Pontiac label. The Scion xB made the list because it's stylish, has the reliability of a Toyota and can carry a lot of stuff for such a compact vehicle.
