Because full-size vans are called upon to perform all sorts of duties, the option list is almost as long as the Savana itself. In these days of abundant standard equipment and multi-feature bundles, it's about as close to a build-it-yourself vehicle as you can get.
The cargo model starts out in an austere way with a 195-horsepower 4.3 V6, two vinyl seats in front, air conditioning (which can be deleted for credit), and sound system components such as speakers and an antenna -- but no actual radio. From that basic point, you can order all-wheel drive, a 310-horsepwer 5.3-liter V8, different audio setups with or without navigation, full power accessories, a rearview camera, more power outlets, various fixtures for the massive cargo bay, and a passel of other features, from the mundane to the highly specialized. All Savanas carry a four-speed automatic transmission with tow/haul mode.
The passenger model comes with the V8 standard and eight-passenger seating, which can be bumped to 12. To make the interior environment more amenable to human occupants, it carries "comforts" such an AM/FM stereo, cloth headliner and visors, and child seat anchors. For families who must have something of this size, GMC offers most of what you could get on a modern crossover, including power front seats in premium cloth, remote start, a leather-wrapped steering wheel, satellite radio and rear climate control.
With the Ford E-Series about to leave the retail market, the Savana and its Chevrolet twin will be the only big American vans available to consumers. They persist because automakers have yet to concoct a modern replacement. The Savana continues to fill a market niche where no other type of vehicle can get the job done.
