Easy, no pressure purchase
Sales consultant; Bob Reasoner, helped me with the car I was looking for. This dealership has a no rush, clarity policy that aloows you to inspect the car to your satifaction and present you with a car that has been safety inspected & detailed. Qualification and rates were resonable.

I had a part go out on my car that was a recall.
I had a part go out on my car that was a recall. I was not able to get it into the shop but they came to me! They had the best service and made me feel like they cared that I chose them for my business.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Everyone was nice and the place was extremely busy.
Everyone was nice and the place was extremely busy. We worked with Nick who was working with 2 sets of customers at the same time, he did a pretty good job of handling both. We test drove a truck and tried to work a deal, but it just did not get down into our price range.
This truck has a jerk when changing gears sometimes.

A very special Thank You to both Chad Sigsworth (Sales
A very special Thank You to both Chad Sigsworth (Sales Associate) and Patrick Amann (Service Associate) who both assisted in the replacement of my engine. Both gentlemen were dedicated from the begining to the end of this replacement. They both stayed right on top of things and kept me well informed until the job was completed. I will always purchase any future vehicles through Dave Sinclair due to their honesty, dedication, and treatment of their customers. They have one of the best staff I ever had the pleasure of working with. Keep up the great work. Sandra Hearn

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.
