Used GMC cars for sale near Penbrook, PA

I was looking for a specific truck- Matt Elliott was more than accommodating - over-the-top. He went out of the way to add the missing pieces to the truckand the results we far better than I expected. Great service all the way around! Highly recommend this dealership!!

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.

From the moment we made the appointment with Adam Whary, to the experience we had driving off the lot with our new 2026 Chevy Traverse, we felt like we were in great hands! The staff we worked with: Adam our sales expert, Jared the sales manager, and Nez the business manager, were friendly, helpful and made sure we understood every step we were taking to lead us into the driver's seat.

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

This is my second Truck purchase at Keller bros and it’s always a seamless process. Nathan found the exact truck I was looking for. The atmosphere is very welcoming and the staff are top notch. You wont find a better group to work with.

Thornton is an awesome place to buy a vehicle! Great dealership, great people to help you with the best buying experience! I’ll certainly be back in a few years!

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.

Test drove and purchased 300c. Troy and Barry are A1. HIGHLY RECOMMEND. And on top PSECU Financed me. Top tier credit. Buying my home now...

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Love the personality of the reps and they are always eager to help! They don't push you into buying more than your original budget and won't bother you about it! They also will let u browse the lot on you own, and all there cars are unlocked! I absolutely love there transfer program where they will transfer vehicles to your local stores without an obligation, and many transfers are free! Only complaint about Carmax is that I feel the cars are a bit overpriced, but it's worth it in the end for there customer service!

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Great no pressure sales. Thorough and detailed explanation of vehicle technology. Easy to work with.

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.

Customer service top notch n friendly. They listened to what we wanted n helped us every step of the way. We love our car we bought!!

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I-Deals Cars was quick to reply toy inquiries and politely invited me to connect to view and further investigate their selection of vehicles.

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.

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!

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Great guys to work with from first contact to picking up our truck. Friendly and low pressure atmosphere. Would recommend to anyone looking for a good used truck!

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

After our serious accident that totaled our vehicle, Amy Troutman worked with us to find the vehicle we were looking for. She is a great person and dealing with her was a most enjoyable experience. Give her a call!

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Thought was just inspection but found problems with sensors and needed repaired. Why do u need twenty five words U can?t submit unless I have 25 words!!!

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.

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.

great service and sales . they do not try to sell me something that is not needed

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. :)

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Everyone was wonderful! They were very responsive and knowledgeable about the vehicle I bought as well as the one I was trading in. Super family friendly and were super accommodating when I had to bring my small children with me! 10/10 would absolutely recommend!

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Thank you Joe…you made the whole transaction for my car comfortable and friendly. I was happy with the way you explained things clearly and broke down areas that were a little confusing and/or hard to comprehend. It was a pleasure meeting you. God bless you and your family. Again, thank you.😊

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.
