When it comes to workhorses, the GMC Savana is second only to the Ford E-Series in design longevity, having been around in its current form since 1997. The Savana takes a decidedly old-school approach to getting the job done: A truck-based frame, 6-liter gas V8 or optional diesel, and a six-speed automatic. In addition to the two engine choices, Savana customers can choose between two wheelbases, and seating configurations for 12 or 15 people. A cargo version is also on offer. It may not have many bells and whistles, and it may not be the most sophisticated driving experience, but the Savana has proven itself to be versatile and dependable, making it a staple of the fleet market.
