Excellent
By Estiva on 7/28/2026 5:46:15 PM
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. I was recently at a family reunion and received compliments on the vehicle. The only thing I miss is the power liftgate I had on my 2019 Chevrolet Equinox. - 5.0
Awesome car
By OHGMCDenali on 2/13/2026 7:18:25 PM
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
Drives and rides great!

It drives and rides great! It has all the bells and whistles you would expect on a denali. The back seats are just as comfortable as the front seats are. The only draw back is the wind and road noise.
