Why it stands out
The 2020 GMC Terrain distinguishes itself in the compact SUV segment with a blend of comfort, safety, and a spacious interior. Owners appreciate its luxurious feel, especially in the Denali trim, which offers premium features and an intuitive entertainment system. The Terrain's design is more angular compared to its Chevrolet Equinox counterpart, giving it a rugged appearance that appeals to those looking for a vehicle capable of off-road adventures. While the Terrain has undergone significant updates, including a redesign for the 2025 model year, it remains competitive with its strong safety ratings and comfortable ride. However, some users have noted that the ride quality may not match larger models like the Traverse, and there are concerns regarding rear passenger comfort. Overall, the 2020 GMC Terrain is an appealing option for buyers seeking a reliable and comfortable compact SUV.
