A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Our salesman Brian Newcome was polite, professional, knowledgeable, and personable. We felt he answered all our questions, and explained the process so it was understandable. When you buy a car you wonder did I get a good price and make the correct decision, with Brian there was no concern about that at all. I would recommend Brian and the dealership to my family and friends.
