Best Vehicle I've Owned
By PC Burger on 4/15/2026 8:22:37 PM
Bought a White Diamond color Denali which has exceeded my expectations. Premium materials throughout, especially seats. The mileage has also exceeded my expectations, have experienced a mileage highway best of 25 mpg, normal highway is 21-22 mpg. My combined is 18 mpg, and I burn regular fuel. Premium is 'recommended', not required.......and I burn that when I tow my boat or jet skiis. Warranty is not affected by this. Ride and Handling is supreme. Safety equipment makes the drivability a super experience. - 5.0
Favorite vehicle we’ve owned
By Smorehead on 8/15/2025 12:50:43 AM
We have owned ours for three years now. We built ours through the local dealer and got everything we asked for. Great fuel economy considering the size and great quality throughout. The interior is very comfortable and well made. We’ve never had an issue other than a couple recalls that have been taken care of by the dealership immediately. We are constantly on the road with our daughter as she plays travel volleyball and there’s plenty of room for all of her things and she can chill in the third row comfortably. Most of the trips are 4 hours one way and on the highway we see around 21-22MPG. Very happy with this vehicle and with the comfort of the 100k warranty we purchased I feel we will be well into the 6 figure mileage range before we make another purchase!
