• Leasing vs. Buying: For businesses or individuals who prefer to upgrade frequently, leasing might be an option, though diesel trucks often have excellent resale value, making buying a strong consideration.

Pro tips from us: Always get a pre-approval from an external lender before visiting the dealership. This provides leverage and ensures you’re getting the best possible interest rate.

3. The All-Important Test Drive

You can read all the reviews in the world, but nothing compares to experiencing the truck yourself.

• Test drive the specific model and engine you’re interested in. Feel the power of the Duramax for yourself.
• Pay attention to comfort, visibility, and ease of controls.
• If possible, test drive with a trailer attached (at the dealership’s discretion) to simulate real-world towing.
