Choose the 2003 Oldsmobile Alero if you want a compact gasoline car with front-wheel drive and automatic shifting, and you can live with its stated fuel budget. The EPA numbers point to better economy on open roads than in city traffic. Its 25 MPG combined figure is the practical headline, while the $2,700 annual fuel-cost estimate helps frame the ongoing expense. The 2.2-liter four-cylinder engine and 355.48-gram-per-mile CO2 figure complete the picture.

How it compares

Who it suits

Trade-offs

Its 25 MPG combined rating gives a clear running-cost reference, while the 21 city and 30 highway figures show how road type changes consumption. EPA's $2,700 annual fuel-cost figure makes fuel spending a major part of the ownership picture.
