• “Lacks refinement and some key safety features compared to rivals, some low-grade cabin materials.” — Edmunds.com
• “If maximum capability and functionality are more important to you than refinement, the 2007 GMC Sierra 3500 Classic is a tough truck to beat.” — Edmunds.com
• “Strong engine choices, multiple drivetrain options, impressive towing and hauling ability.” — Edmunds.com
• “The available engines include a relatively refined, Isuzu-developed 6.6-liter turbodiesel V8 mated to a smooth six-speed automatic. A huge 8.1-liter V8 is also available. These trucks are intended for commercial use or heavy-duty towing.” — Consumer Reports
