Why it stands out

The 2020 GMC Terrain distinguishes itself with a unique blend of comfort and style, tailored for both city driving and off-road adventures. Its spacious interior caters well to families and passengers, reinforced by high safety ratings that put it in the spotlight among compact SUVs. While it shares much of its platform with the Chevrolet Equinox, the Terrain's aesthetic leans towards a more rugged, angular look, especially in its AT4 variant, enhanced for off-road capability. The luxurious Denali trim further elevates the Terrain's appeal with upscale materials and features. However, the Terrain does face criticism regarding second-row passenger comfort and comparison with larger models like the Traverse. Despite these aspects, its overall value, especially in relation to pricing and reliability, makes the 2020 GMC Terrain an attractive choice for potential buyers.
