2021 GMC Terrain
S.M., 06/10/2021
2021 GMC Terrain SLT 4dr SUV (1.5L 4cyl Turbo 9A)
It’s been a about a month with my 2021 GMC Terrain and I absolutely love it. It’s not the fastest car in the world but it’s 4 Cylinder engine can actually run hard and smooth at the same time. As far as the milage it runs on gas, I honestly can’t complain. it’s the perfect size efficient vehicle anyone can ask for.
