Used Cars: Midsized Sedans Under $20,000 With the Best Fuel Economy

These reasonably priced and reliable cars prove you don't need to get a hybrid for great mileage

Buying a well-maintained used vehicle can be a smart move because used cars have gone through the most significant part of their depreciation cycle by the time they’re 5 years old. This means you’ll get many of the modern convenience and entertainment features found in brand-new models but at a significantly lower price.

They were also designed and built recently enough that their performance in our tests—such as acceleration, braking, and fuel economy—is still on a par with brand-new cars. But rather than having to spend $30,000 (or more) for a new version, these can be had for less than $20,000 depending on the make and model.

To help steer you to the best choice, we’ve assembled a list of the six most fuel-efficient 5-year-old nonhybrid midsized sedans. All performed well enough in our tests to be recommended when new, and all have average or better reliability, according to CR’s Annual Auto Surveys, where we ask CR members to tell us about what went wrong with the cars they own.
