Most Sierra buyers choose financing, especially drivers who put on high mileage, tow regularly or plan to customize their truck with lifts, wheels, hitches or bed accessories. Financing lets you build equity and keep your truck for the long haul.

Leasing can be a smart choice if you want a lower monthly payment and like upgrading to a new truck every few years. Lease specials are often available on select Sierra models.

Frequently Asked Questions About the GMC Sierra

What’s the difference between the GMC Sierra and the Chevy Silverado?

The Sierra and Silverado share a platform, but the Sierra offers more premium styling, upscale interiors, and exclusive features and trims like Denali, Denali Ultimate and AT4X.

How much can a GMC Sierra tow?

Towing capacity depends on the model, engine, cab, bed and axle configuration. The Sierra HD offers the highest towing capacity, especially with the Duramax diesel. Ask our team for the exact rating on any truck in our inventory.

Should I get a Sierra 1500 or Sierra HD?

Diesel engines offer strong torque for towing and excellent highway fuel economy, which makes them popular with drivers who tow often or drive long distances.
