CarGurus Analysis: 2018 GMC Terrain

Picture of 2018 GMC Terrain ## Summary - With 1,872 currently listed for sale on CarGurus and an **average price of $14,381.00**, 32.0% of 2018 GMC Terrains for sale on CarGurus are rated as good or great deals. - **Favorably reviewed:** Owners rated the 2018 GMC Terrain 4.54 / 5 stars. - **62.1% of 2018 Terrain models on CarGurus are accident free**. - The 2018 GMC Terrain features a redesigned look and offers a range of trim levels and engine options to suit various preferences. ## Why it stands out The 2018 GMC Terrain distinguishes itself with a fresh design that aims to appeal to a broader audience while maintaining GMC's "Professional Grade" branding. Unlike its predecessor, the Terrain has shifted from bold and boxy aesthetics to a more conservative and modern profile. This model year offers a choice of three turbocharged engines—including a powerful 2.0-liter option—and two drivetrains (FWD and AWD), providing versatility for different driving needs. Owners appreciate the Terrain's comfort, spaciousness, and variety of features, particularly in higher trim levels. However, some critics point to issues like sensitivity in brake response, occasionally lacking power under certain conditions, and concerns regarding its pricing strategy, which some find questionable against rivals. ## Other model years to consider - **[2023 GMC Terrain](https://www.cargurus.com/Cars/l-Used-2023-GMC-Terrain-c32471)** - Average price: $23,432.00 - Good/great deal percentage: 29.7% - User rating: 5 / 5 - Total listings: 5,006 - **[2024 GMC Terrain](https://www.cargurus.com/Cars/l-Used-2024-GMC-Terrain-c33045)** - Average price: $23,459.00 - Good/great deal percentage: 30.3% - User rating: 5 / 5 - Total listings: 4,220 - **[2021 GMC Terrain](https://www.cargurus.com/Cars/l-Used-2021-GMC-Terrain-c30365)** - Average price: $18,594.00 - Good/great deal percentage: 32.4% - User rating: 5 / 5 - Total listings: 2,633 This analysis is based on CarGurus' proprietary market data from March 2, 2026, CarGurus experts' opinions, and generative AI.

It’s the Denali so it has everything you need plus more. Only thing that would make it better would be a V6 but this 2.0 turbo has major get up and go.

The car is amazing and of great value. We purchased this vehicle for under the market value and it is in excellent condition. I did a thorough walk around and probably looked like an idiot looking for the smallest dents and scratches. The vehicle has great options, panoramic roof and good quality materials, especially for the price. What a steal my wife got!!!!
