This 3rd Tahoe for us and is the nicest family car we have ever owned. Comfortable, quiet, and 19 to 20 miles per gallon using cruise control and driving in a sane manner. The fuel management system really helps with the gas. Runs on Regular. Easy to use controls. Memory seats. Dual zone heating and cooling. Both I and my wife are comfortable.
For a SUV it has the best feel and handling of any I have driven. Navigation system. Easy to use and easy to understand. Heated seats and remote start in the winter. XM radio is nice and the On Star system makes me feel secure with the kids on trips.
