"My particular Escalade is a 2007 ESV with all the options except for the Captians chairs for the middle row. I bought my Escalade used in 2008 to replace a 2006 Suburban that was unsuitable for Alaska weather since it was only 2 Wheel drive. The Vehicle has a great combination of power and comfort that is unmatched by anything else I have ever driven.
I have pulled travel trailers and car trailers through the Denali mountains, and to Chichina AK averaging nearly 14 MPG. I know a Escalade is a luxury vehicle not normally used for pulling but when you have over 400 HP and 400 lbs of Torque why not use it. I will say the City Mileage from the 6.2 Liter is terrible but it more than makes up for it on the Highway were I have gotten as high 23.5 miles MPG on a 900 mile round trip from Fairbanks to Anchorage.
Mechanically the Escalade is as sound as anything else out there. I have had a few problems with the electronics though my DVD changer quit working and destroyed some disc and I had it in the shop 5 times for issues with the heated seats but over the last 6 months I havent been to the dealership for anything other than a oil change knock on wood.
If your looking for an amazing ride with plenty of capability and you can afford it I would highly recommend the Escalade to anyone."
