GMC Savana Conversion
Least efficient cargo van
EPA City/Highway: 12/16
The GMC Savana and Chevrolet Express Conversions are perfect if you're not ready for an RV. They swallow up to nine people and the hightop model pictured here even lets them stand up inside.
They're great cruisers, but take them long distance in 2008 and you won't have enough credit on your Visa to buy a pack of beef jerky.(Conversion Van Marketing Association)
