Why it stands out

The 2020 GMC Terrain is distinguished by its combination of comfort and safety features, which have earned it praise from owners. Many appreciate its spacious and plush interior, particularly in the luxurious Denali trim, which offers a sophisticated feel and an advanced infotainment system. However, there are some caveats, such as its less favorable ride quality compared to larger SUVs like the GMC Acadia and criticism regarding rear passenger comfort. Furthermore, the Terrain has a reputation for poor resale value compared to competitors, presenting an appealing opportunity for budget-conscious buyers. While it shines in comfort and technology, its lack of hybrid options compared to rivals like the Honda CR-V and Toyota RAV4 may deter some environmentally conscious buyers.
