overall
Summary
With 1,127 currently listed for sale and an average price of $49,670.00, 29.7% of 2020 GMC Sierras 2500HD for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2020 GMC Sierra 2500HD 4.86 / 5 stars and CarGurus experts gave it an 8.17 / 10.
75.4% of 2020 Sierra 2500HD models on CarGurus are accident free.
Why it stands out
The 2020 GMC Sierra 2500HD stands out as a heavy-duty truck with a luxury-leaning Denali identity. It is described as one of the most expensive trucks on the U.S. market, and also as one of the most capable and upscale trucks offered by General Motors. That combination gives it broad appeal for buyers who want serious truck ability without giving up a more premium feel, and the available features help reinforce that mission.
At the same time, the 2020 GMC Sierra 2500HD is not presented as a perfect luxury experience. The test-drive data says it drives great and is loaded with features, but its fit and finish do not live up to “luxury truck” billing. It is also called out for poor value for money and interior materials that feel cheap. Even so, the truck’s multiple powertrain options and plenty of cargo space make it a compelling choice for shoppers who prioritize capability and utility, and owner feedback echoes praise for its performance, comfort, towing capabilities, and power.

Looks great but a little pricey for the year. Even though it has low mileage. I would buy a newer truck.

The GMC 2500 HD is the truck for me. Like all the other major brands of trucks the price is in the same range. The diesel engine and 4x4 is about good as it gets. For work or play GMC is the way!!
