You already know that the 2023 GMC Terrain is a popular small SUV, but how much do you know about the exterior? The SLE is the base model. Both it and the SLT come with LED headlights and taillights. All lights feature the signature C-shaped design from GMC, which pulls the eye toward the chrome grille. This grille uses a combo of chrome accents and sharp lines to set it apart from other SUVs on the road. While you might think the 19-inch wheels are standard, they have a glossy black paint job that adds a touch of class. You'll find 19-inch machined wheels on the Denali, 17-inch aluminum wheels on the AT4, and 19-inch gray wheels on the SLT. The Terrain also has roof rails that add storage when you need it. Customize the exterior with your favorite paint color and/or the addition of a tow hitch.
