Used GMC cars for sale near Londonderry, 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!!

Everything I want in a vehicle. I love the interior and the slick look of the overall vehicle itself. Oh can’t forget about all the different options Available on this truck. It has so much to offer!

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.😊

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!

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!

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.

The buying online experience was top notch , no xx like a normal experience at a car dealership . Highly recommend these guys to buy your next vehicle .

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.

Awesome service! Staff knowledgeable and professional. Very friendly. I would purchase from them again. Referred another customer to them as well

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

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!

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.

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

I accompanied my husband to pick up our new car. The dealership staff was friendly and professional. The physical layout was spacious and comfortable during the final pickup phase. Code insured we understood the features of our new car, making sure we knew to contact him with any questions after leaving the lot.

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.

Excellent to work with! No pressure sales and answered all my questions through out the entire process! Great selection to choose from. Highly recommend them!!

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!

Hernan (sales) was great to deal with. Very professional and efficient. Let me test drive used Audi without accompanying me which allowed me a little more time to fiddle with everything, become comfortable and make sure it was the right car for me. No pressure and the manager worked with me on trade value. Finance mgr was also efficient and transparent; offered extras (GAP, extended warranty) but did not pressure me at all to buy. When a car dealer presents as a professional establishment which respects your budget and time, it makes for a much more pleasant experience. Kudos to Autohaus Lancaster!

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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 truck dealer! They are giving me a solid price for my trade. They have great deals on a large selection of inventory! My deal is pending only due to the Coronavirus. Thanks a lot Zach!

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Friendly and fast service. No small writings for extra fees. Great company and employees.would do business with them again if I ever wanted a new vehicle.

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.

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!

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

Exceptionally friendly salesperson (Hans) - great quality autos - easy to find and very appropriate follow up after my visit and test drive.

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...

Paij Hall was very professional and helpful when we purchased our Rav4 from Bennett Toyota of Lebanon. He explained the vehicle very well and followed up with us to see how things were going. He met our expectations.

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

All the Mazda representatives we were in contact with were good with their presentation of the Mazda CX-30, the car that we were interested in and were not pushy.

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.

Rachael our sales woman was very nice and pleasant. She never pushed! And that is what I look for. A good salesman give you breathing room and that’s what she exactly did.

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!

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.

It was wonderful They explained everything perfect Very friendly and nice I would recommend them to anyone

The gmc Yukon from 2014 is very good it’s good for snow hauling trailers and children. What I love is the cozy luxury interior with the leather seats. It is very reliable the biggest problem we had was the cooling system failing but the repair cost was only $200. I kept everything on it stock. The sound system speakers are crazy good the base is 200% good I just love everything about it!
