I purchased my truck from DeMarois 3 years ago. I took my truck in for warranty service a couple of times. The service department (and especially Ivory the service writer) have been great to work with.

Excellent customer service! We had problems with our Sprinter van and had to be towed in from Glacier National Park. Inspite of their already busy workload they were able fit us in and get us back on the road and our vacation in a short period of time. Thanks guys!

Best purchase experience I’ve had in over 5 decades of buying numerous vehicles, including Jeeps, Dodge RAMs, Corvettes, Porsche, Land Rovers, and Mercedes. Friendly, helpful, knowledgeable salesman. Lew did everything promised and had purchase paperwork ready when we showed up to complete purchase. If I were ever to buy another Mercedes, I would definitely go to DeMarois.

I was traveling and had transmission problems. they made an appointment for me the next day. I got stuck in traffic when going there and was 40 minutes late. They still got me in, fixed my issue at a reasonable price, and got me back on the road. Thanks Demoris GMC service
