Used GMC trucks for sale near Warminster, PA

Grisell Sierra did a fantastic job of making sure I get all the right information about the car and making sure i was comfortable on the purchase of the car. She was absolutely amazing and I would love to have her every single time I get a new car.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Good experience. I leased a 2025 Gladiator Mojave. Cody and Crystal were very easy to work with. The dealership is an hour and twenty minutes away but I’d say it was worth it.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Fixed a intermittent battery drain that was driving me nuts. Service Technician (Anthony) really went the extra mile to repair. Can't speak more highly of service team.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Angela was great very knowledgeable and kept the process moving along. Dealership was beautiful and everyone was very friendly

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. :)

Great experience. Dan Cirotti was extremely helpful and listened to our concerns. We LOVE our car! Will continue to recommend Carshop. We were able to trade in our two cars!!! What a relief. Thanks everyone and especially Dan Cirotti.

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.

Honest and very transparent. Everything was explained in detail and the staff was very friendly. Highly recommend Star for all your truck needs.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

I’ve had my share of crap with dealerships. I had the pleasure of working with a very patient knowledgeable salesman “John” at this location. He helped me locate the vehicle I wanted in a timely manner. It arrived and was taken care of the entire process. I received fair market value for my trade. There was no need to haggle just sign and drive. I highly recommend this place if your looking for a quality used car. This vehicle is almost new. That’s because carmax cares about what they sell. If you know your price ahead of time this is your place. They got me out the door in less than 2 hrs. Those of you who have purchased cars that could be an all day affair. Everyone was friendly . I can’t say enough good things. There’s no dealership that could compare to carmax. This place met my expectations.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Great dealership to work with i was in and out in 45 minutes. Will deal with again

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

I have had the blessing of dealing with James Kovack two times - once in connection with the sale of my leased 2021 RAV 4, the other time witnessing the sale of my sister's 2021 RAV 4. At that time ( my sister's visit) based on my experience, she requested James to work with her. My sister's experience and mine mirrored each others. James was kind, patient, respectful, efficient, knowledgeable, and possessed all of the attributes one would expect in dealing with someone in his position. My sister's experience required a little more work and James, in consultation with his supervisor, Qu'ran Gordon, got the job done. Both men were as courteous and respectful of the situation as they could be and both men should be considered ASSETS to Carmax of Langhorne. My sister and I are most pleased with the outcomes of both of our experiences and will recommend Carmax, but in particular James Kovack and Qu'ran Gordon for their fine work.

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!

the best, had a great experience and it was the cheapest car on the internet

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.

I love this dealership and the service they provide. The people are very friendly and courteous. I would definitely recommend this dealer to a family member or friend

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

Greg is a GREAT salesman I used him twice and each time we made a deal… please asked for him when you go to the dealership.. highly recommend..

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Toyota care service was done as scheduled and completed before promised. It usually does not work out this way and is refreshing when people do what they promised.

It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility. Overall very comfortable ride and smooth drive

This is the only place I will go to buy I car. They went above and beyond for me to drive and afford a brand new car. Mike took his time to show me how everything worked in the car, made3 sure I was comfortable, and truly was easy to work with and never pressured me into anything I didn't want. Mike, Jason, Alex, everyone was phenomenal. I have recommended them to so many people and will continue to do so.

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

I had a great experience with Mainline, even though the process was not easy these guys made it very easy for me and surprisingly the team is very multicultural. There isn’t a language that they don’t speak which makes it very convenient. Thank you to sales Reps!!!

The purchase was easy, left a good impression. I was looking for a car in good condition and at an adequate price. I found just such an option at Excel Auto Lounge. The car was shown in detail, the employees were polite. Everything is great.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

It was a quick and easy process, Heni was the sales rep, and he was very professional and nice.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Great service, Mr Mike Kilgus was OUTSTANDING, could not have been any more helpful, cordial, and knowledgeable! Will ALWAYS cone to Chapman for service! GREAT!!!!!

My experience purchasing my car was a 5 star with Mike Keene, from the time I came through the door until the time I walked out! Mike went above and beyond helping me to set up my radio! Mike is definitely a 5 star with my experience with Piazza Honda Thanks Mike!

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Received PA inspection and four replacement tires- all done one stop. Love the convenience of Saturday hours. It makes my life easier. Have I gotten to 25 words? YES LOL!

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.
