What people say
The 2025 GMC Sierra 2500HD stands out as a more refined and upscale version of the Silverado 2500, offering the same impressive power and towing capability with added luxury and tech touches. Its interior feels more premium, benefits from features like the MultiPro tailgate, and has a slightly smoother ride.
Outstanding vehicle! Has everything I expected and has a lot of capabilities.
Absolutely love the truck and it was at a good price for the amount of miles and condition!
I’m not a fan of black. This truck had a black exterior and interior. It’s not for me. GM should offer more color choices.
Entire undercarriage is covered in rust. All control arms and linkages are in extremely poor condition from rust to the point I wouldn’t feel safe driving it. Let alone using it for its intended purpose for heavy duty towing.
