Used GMC Sierra 1500 trucks for sale near Sumner, ME

They were able to diagnose the issue I was having. They were able to do the repair. I was pleased with the the way the service manager helped me

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

We worked with Justin and he was amazing! He kept us informed about the car we wanted and was able to get us more than expected for our trade in.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

To start off with... Dean was awesome!! no pressure he was all alone when my wife and I stopped in, and very busy. But he took a second to acknowledge us. We were there about an hour and a half and left with a 2008 Tahoe. Simple, Fast, Easy !!! the way it should be. I would have felt better if Dean let me "beat" him up on the price a little more but I still feel i got a good deal!! LOL. I think it is funny reading the other reviews, because we had just came from Brunswick Ford too (I'll never go back).

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I was particularly impressed by Derek who went out of his way to ensure my car purchase paperwork was completed before I arrived for the 2026 GMC Sierra 1500 Denali Ultimate I was purchasing. I arrived and within 10 minutes I was in the finance manager?s office finalizing the sale. Couldn?t be happier about my experience.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

This will be my 4th GMC truck purchase from Chuck Poulin at Lee GMC. He is a very straight forward and easy to deal with salesman. I very much appreciate doing business with him, and plan to again in the future.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.
