New and used 2026 GMC Sierra 3500 trucks for sale near Monroe, NH

Mike Salvalty was extremely helpful in getting us in a new truck at what we wanted to have for a monthly payment. He took care of us while working with another couple picking up a vehicle and still gave us great service. I would highly recommend anyone to visit Mike at Capitol for a new car.

Everybody is very friendly and helpful. The work is timely and complete.

Kind and skilled professionals. They made me feel comfortable and explained everything so that I understood the process and felt confident in my decisions. I highly recommend these people. They checked in after the sale and made sure I knew they were there for me if I needed anything to do with the car. Excellent dealership.

When you're looking to trade in or trade up your current vehicle be sure to stop at this dealership. They gave me a great value for my vehicle and I left with a lower payment and a car that I am so happy with! Friendly service and I feel confident going to them for my vehicle needs. They're right in the heart of Vermont, near Montpelier and are amazing folks to work with.

Karl, our salesman, was very honest and fair while we weighed our options. They gave us a great deal on our trade and put us in a fair priced vehicle. Highly recommend working with Karl.

For as long as I've been going there it has been exceptional service and this time was no different. They are always friendly and helpful. The work is done efficiently and in time. They diagnosed the major issues for my Ford years ago which led me to trade in for a GMC and have stayed since. They know their customers and their needs. They do need a vending machine :)

When our son graduated from college this past May, we knew he would need a reliable vehicle to get back and forth from work. Already having two vehicles from St J Auto, we knew where to go. Daniel fell in love with the 2020 Buick Encore GX on the lot. We set up an appointment to test drive the car. Doug, one of the sales managers was great to deal with. He answered all our questions, and I was pretty persistent on a few questions, thank you Doug. The buying experience was made easy by the staff at St J Auto, and we thank them for that. The lady in finance (sorry, forgot name) answered all our questions and got us to a final price we were happy with. After taking the car home, we ran in to a few minor problems and also had a minor recall on the Encore GX. The employees in the service department were great to deal with, Denise, Jackie, and Zac all helped us with the issues. There were a few things we didn't understand what was going on with the recall and all, but in the end the staff at St J Auto once again did a great job getting us through another car buying experience.

Due to the current truck shortages dealers have been adding $5-15,000 over MSRP but you guys stood by your MSRP price. They also met me in NY at airport with my truck to save 5 hours off of my return drive. Couldn’t have asked for a more simple process and great team to work with. Thank you for all the help.

I called the sales department at 7 am. Was greeted by Emma. Confirmed the truck I wanted to look at was available. Upon arrival I was not overwhelmed by a salesman in the lot. Excellent. Once I went inside I was promptly greeted by Emma who remembered me calling and immediately had the truck I wanted to see ready for my inspection. Very professional young lady and very down to earth. Next I was greeted by Dean in sales who was a great guy. No pressure whatsoever from him. Tested the truck. Asked for a price. Got it ASAP with no xx. Great guy. Deans attitude and honesty sold me. Haven’t been in a dealership like this before. Honest real people. Not the fake people trying to get your money. I was next introduced to any in finance and she was very professional and very pleasant. Just wish I got to meet her dogs. Overall best experience buying a vehicle I have ever had. They have my business. Can’t go wrong hear. Thanks GMC team.
