CarGurus Analysis: 2021 GMC Terrain
Summary
With 155 currently listed for sale near Garland, TX and an average price of $18,455.00, 31.6% 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.
93.5% of 2021 Terrain models on CarGurus are accident free.
Why it stands out
The 2021 GMC Terrain stands out as a compact SUV that leans into comfort, convenience, and value rather than chasing class-leading space or performance. It offers a smooth ride, a roomy cabin for four adults, and a feature set that includes a large touchscreen, a digital driver information display, heated front seats, and a heated steering wheel. GMC also gave it a strong safety and driver-assistance roster for the year, along with Teen Driver technology for families who want more control over new drivers.
What makes the 2021 model especially appealing is how much equipment it brings without feeling stripped down. Front-wheel-drive versions use a continuously variable automatic transmission, while all-wheel-drive models switch to an eight-speed automatic and gain additional drive modes. The Terrain also delivers respectable fuel economy for the class, and its towing capacity reaches 1,500 pounds with all-wheel drive. Buyers who want a compact SUV with a polished interior and a long list of standard features may find that combination compelling.
The Terrain is not perfect, though. Cargo space is on the small side for the segment, and the model does not offer a hybrid powertrain. Still, for shoppers who value a comfortable daily driver with a modern cabin and a good balance of efficiency and equipment, the 2021 GMC Terrain has a clear appeal.

It had everything and more in the features that I was looking for. I think it was a good value for all that it offered.

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.
