CarGurus Analysis: 2021 GMC Sierra 1500
overall
Summary
With 6,815 currently listed for sale and an average price of $35,576.00, 32.8% of 2021 GMC Sierras for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 GMC Sierra 1500 4.9 / 5 stars and CarGurus experts gave it a 5.67 / 10.
81.6% of 2021 Sierra 1500 models on CarGurus are accident free.
Why it stands out
The 2021 GMC Sierra 1500 stands out as a full-size light-duty pickup that mixes familiar capability with a few distinctive GMC touches. It shares its basic hardware with the Chevrolet Silverado 1500, but it wears different styling and offers unique features such as an optional carbon-fiber composite cargo bed. It also comes in multiple body styles and with multiple powertrain options, which helps it appeal to buyers who want flexibility in how they configure their truck.
What makes the 2021 GMC Sierra 1500 especially interesting is that its strongest setup may not be the one most buyers expect. Unless you can’t live without the deeply satisfying rumble of a V8 engine, it is at its best when equipped with the affordable Duramax turbodiesel inline-six. The truck also earns credit for easy-to-use technology, though it is not without drawbacks: the technology is described as outdated, the interior materials feel cheap, and the base engine is underwhelming. Even so, it remains a fundamentally appealing truck, with the main caveat being that it needs attention to the details.
