Pick the Alero if your priorities are a compact car, front-wheel drive, and a manual transmission rather than an automatic. The EPA figures point to moderate fuel use overall, with noticeably better mileage on highways than in town. Its yearly fuel estimate is $2700, so fuel spending remains a central ownership consideration. The gasoline engine and recorded tailpipe emissions also make this a conventional choice rather than a low-emission alternative. Drivers whose travel is mostly highway may find the 30 MPG rating more relevant than the 22 MPG city figure.
