2023 Terrain SLT AWD with 96,000 miles. I’ve had since new, and maintained exclusively at my local Chevrolet/GMC dealer. Most of my miles are highway, but I’m averaging 32 MPG, and have had NO issues. I had the tires replaced at 80,000, it still has the original brake pads. This vehicle still drives like new.

Awesome car

This purchase has turned out to be the best thing I did in car purchasing in a while. I enjoy the ride, the comfort and the equipment. Its not a rocket ship but who needs an SUV to go from 0 - 60 in 2 secs? If you need that stay in a sports car. You'll love this well made SUV… - 4.0
