CarGurus Analysis: 2021 GMC Sierra 1500
overall
Summary
With 562 currently listed for sale and an average price of $40,255 CAD, 33.1% of 2021 GMC Sierras for sale on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2021 GMC Sierra 1500 4.9 / 5 stars and CarGurus experts gave it a 5.67 / 10.
100.0% 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 leans on distinctive styling and a few unique features rather than a wholesale reinvention. GMC’s “professional grade” positioning is mostly marketing language, but the truck does separate itself from its Chevrolet counterpart with different styling and an optional carbon-fibre composite cargo bed. That gives it a more individual identity for buyers who want a familiar pickup formula with a slightly more premium presentation.
What makes this truck especially appealing is that its strongest character comes from the powertrain choice highlighted in the source material: unless you cannot live without the deeply satisfying rumble of a V8 engine, the 2021 GMC Sierra 1500 is at its best with the affordable Duramax turbodiesel inline-six. The same source also notes that this year brings several changes, though none are earth-shattering, which suggests the Sierra’s appeal is more about refinement and detail than dramatic transformation. Overall, it remains a fundamentally appealing truck, but one that benefits from careful attention to the details.
