Summary
With 2,648 currently listed for sale and an average price of $18,673.00, 31.5% of 2021 GMC Terrains for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 GMC Terrain 5 / 5 stars.

The 2021 GMC Terrain is praised for its stylish interior, smooth ride, and fuel efficiency, although some owners noted minor omissions like the lack of a standard auto wiper feature.
Why it stands out
The 2021 GMC Terrain distinguishes itself in the compact SUV segment with its stylish design and a well-appointed interior that appeals to buyers looking for both comfort and functionality. It shares its platform with the Chevrolet Equinox, but the Terrain's more angular styling gives it a rugged appearance, especially in the AT4 trim designed for off-road capability. The Terrain is equipped with a suite of safety features and technologies, making it a solid choice for families. While it lacks a hybrid option, its fuel efficiency and smooth ride are significant advantages. Owners appreciate the value it offers, although some have pointed out the absence of certain features that competitors might include as standard.

Very nice interior. Excellent options. We went with a black on black model but would have purchased this one if the other had not been available.

I absolutely adore my Terrain! I love everything about it. Not too big, not too small. Zero complaints. If I did have to make a suggestion I would say blind spot protection, and maybe a bigger screen that shows your speed but not deal breakers and simply just suggestions :)

I love the Terrain! It drives great and has a smoothest ride. It also is good on gas.
