2018 Is the Best Year for GMC Terrain

Many of our shortlisted models were from the recent Terrain years. However, we ultimately decided on the 2018 model because it provides a good balance of reliability, bells and whistles, and value for the money. For starters, the 2018 model launches the second generation of the GMC Terrain and a significant overhaul of the SUV.

The 2018 model year marked the time when the Terrain turned into a compact crossover from a midsize SUV. Therefore, it’s built on a new platform in line with most modern SUVs. It’s smaller but still offers competitive interior seating for five passengers. In addition, the interior was also updated to include a newer look, soft-touch materials, and an updated infotainment system.

With its accessible pricing, the 2018 model is our best year for GMC Terrain.
