5 reasons to buy the 2020 GMC Terrain

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

GMC Terrain: Front Seats | CarMax

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.

4. More Driver-Assistance

GMC Terrain: Tech Dash | CarMax

The latest tech to help you on your day-to-day commute is available right here on the 2020 GMC Terrain. Standard on all trim levels is the GM Pro suite of driver-assistance features. This includes automatic emergency braking, forward-collision alert, following-distance indicator, lane-keep assist with lane-departure warning, IntelliBeam headlamps, and front pedestrian braking.

5. Cool elevation edition

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." Available as a package on the SLE and SLT, it comes with 19-inch gloss-black aluminum wheels featuring black GMC center caps with black GMC lettering. There's also a darkened front grille, plus black roof side rails, mirror caps, and exterior badging. That's definitely a great way to make an entrance.

GMC Acadia

The GMC Acadia is a great midsize crossover that seats up to seven and comes with lots of cool features. The 2017 model year started the Acadia's second generation and the SUV got a bunch of upgrades. Choose from the standard 193-horsepower 2.5L four-cylinder, or opt for the 3.6L V6 which is good for 310 horsepower. Both powertrain options are available with all-wheel drive. Start with the 2019 Acadia base model SL/SLE-1 or move up the trim levels to the upgraded SLE-2 which adds standard features like an eight-way power driver seat, heated front seats, and a remote vehicle starter system. The All-Terrain trim adds standard AWD and then you can step up to the more luxurious SLT-1 and SLT-2, both with standard leather seating, or opt for the cool Acadia Black Edition or the top of the line Acadia Denali. The GMC Acadia lineup has something for everyone.
