Frequently Asked Questions

What's the difference between the Sierra 2500HD and 3500HD? +
The key difference comes down to maximum towing and payload capability. The 3500HD is built for the most demanding loads, offering higher overall capacity and the option of a dual rear wheel (dually) setup for added stability and control when hauling at the upper limits.
How do I know which Sierra HD is right for me? +
It really comes down to how you plan to use the truck day to day, especially your typical trailer weight, how often you're towing, passenger and cab space needs, and whether it's primarily for work, personal use, or both.
Should I choose gas or Duramax diesel? +
Gas engines typically offer a lower upfront cost, simpler maintenance, and are well-suited for occasional towing and everyday use. The Duramax diesel, on the other hand, delivers significantly higher torque and is better suited for heavy loads, frequent towing, and long-distance driving where maximum capability matters.
Can I trade in my current vehicle towards a Sierra HD? +
Yes, Sherwood Buick GMC accepts all makes and models. Your trade-in can be applied directly toward the purchase or lease of your new Sierra HD, helping reduce your overall cost and simplify the upgrade process.
