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!… - 5.0

Just bought a used 2022 SLT
By Taylor | on 4/29/2024 1:10:32 AM
Our family has had a 2017 Tahoe for the last 3 years. We sold it at 100k and bought a ‘22 SLT with $27k miles because we lived out Tahoe so much - especially on family road trips. I never did any research or read reviews until after we bought. I am blown away at the technology, comfort, ride, features, and attractiveness of this car. We could not be happier and frankly I’m thankful we could afford a car this nice. It even has 4WD for the occasional use for work (I’m in the landfill business). The denali has much nicer leather and the seats could definitely be cushier, but the interior quality and sunroof blows me away. I can not speak to the quality except to say ours had only 2 minor recall issues. Highly recommend based on my week of ownership. Hope it stays that way….fingers crossed…
