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.… - 5.0
