I highly recommend this vehicle. The performance is outstanding and the vehicle is extremely comfortable. We bought a Honda Pilot as a second car and it fell way short of the Tahoe. The gas mileage isn't great, but no one should really expect great gas mileage from a vehicle of this size.
Very comfortable vehicle and the fact that it has never had a breakdown or needed repair other than routine maintenance.
The adjustable side supports on the front seats can be a little annoying. Also, the arm rests need to be a little higher or should be made to adjust higher for us taller folks.
