"I have not owned this vehicle but hired one from hertz for 5 weeks in Sep 09. With 4 adults and 2 children the originally booked GMC was adequate for the passengers but not luggage. After upgrading to the expedition EL we had adequate room for both passengers and baggage - and we dont travel light. The vehicle was used in the bay area and la region as well as lots of highway miles in CA, NV, UT and the engine never missed a beat. The mixed fuel economy was in excess of your tests averaging 16.5mpg over 5000 km and the vehicle is comfortable if not stylish. The only criticism is the third rwo A/C vents seem to self close all the time finally fixed with chewing gum!!! We will specify this vehicle again and I would buy one.
The push button third row fold is excellent.
The vehicle handles well and cruises effortlessly."
