My 2007 Tahoe is a joy to drive! It's extremely comfortable for both the driver and passengers. Lots of cargo space and the flexibility of adding the 3rd row seats. It's a big SUV -- not purchased for its fuel economy -- but I still beat the 16mpg rating even with most of my driving in town for less than 8 miles per trip.
My favorite is "the feel"...I don't know how else to explain it. It's substantial, responsive, and comfortable.
I would love for Chevrolet to add the key pad entry on the door handle that most Ford models have.
