5 Reasons to Buy

1. Interior Versatility

GMC Terrain: Backseats | CarMax

All trim levels of the 2020 Terrain have a flat-loading floor, meaning that both the second row and the front passenger seat can be folded flat. This opens up the option to place items that are up to eight feet in length into the Terrain. This makes trips to the grocery store or camp site comfortable and convenient.

2. Available AWD

All-wheel drive is a great option on any SUV or crossover. All trim levels of the 2020 GMC Terrain, except the base SL, can be optioned with AWD. That means peace of mind and more confidence in tough weather for you and your passengers, whether it's just around town or on an epic road trip.

3. Upscale Denali Trim

The Denali trim has been a staple in the GMC lineup for quite some time. Representing the top tier in luxury and equipment, the Terrain Denali is pretty impressive. From a heated leather-wrapped steering wheel to french-stitched leather trim and burnished-aluminum accents, the interior of the Denali is very upscale. Outside, you'll get cool LED headlights, a unique grille, and additional chrome trim. You can even add the Denali Premium package which adds optional features like ventilated front seats, adaptive cruise control, and a surround-view parking camera system.

The 2020 Terrain is already a cool looking SUV. But if you want to elevate the appearance of your Terrain a bit, check out the aptly-named "Elevation Edition."
