Used GMC trucks for sale near Cornwall, PA

Raul was very up front with what twin pine could offer. It made purchasing my truck very easy. I would recommend Raul and the dealer ship to friends and family. Prices were fair and we didn’t feel pressured to buy extra add on thanks to Adam.

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.

My experience at the dealership was fantastic, warm welcome at the front desk, and management was considerate and helpful, very clean and professionally run operation. plenty of outstanding selection of vehicles to choose from.

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

Always have a great experience with Keim Chevrolet. No pressure atmosphere, just helpful people looking to keep you safe on the road. Thanks!

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. :)

Overall GREAT place to deal with! I've purchased 3 new vehicles there and have been very happy!!!

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!

The process was very seamless & went very well. The only thing I have to complain about is the actual price was a little higher than the advertised price which was my own fault.

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.

We had a wonderful experience with Jordan @ Mark Martin. As an out of state buyer I was bit apprehensive but Jordan worked with us at every level and was very helpful in answering questions as well as timely communication back and forth. The vehicle was delivered last week and was in great shape, matching the description and images on the MM site and cars.com. We ended up using Lemon Squad to go through the vehicle and provide a report on the vehicle. No major findings and felt even more comfortable we were getting a good vehicle. Thank you again to the team at Mark Martin and especially Jordan!

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.

I just purchased a Mazda 3. I want to Thank Robb Dorf for making the sales so easy and with no sales pressure.

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.

The Sales Manager Jonathan was super helpful and easy to work with. They took the time to show me all of the vehicles that I was interested in with no pressure. I would highly recommend this little gem of a dealership. The dealership is small, but they are building a brand new store nearby.

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

Great sales and service. Had an excellent experience buying a new used vehicle for myself.

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...

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!!

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.

Very helpful and compassionate. Car I looked at was great! Would definately go back if I was in the need again. Adrian was wonderful!

Luke and Jake are always on top of things! Great job to everyone at Keim Chevrolet!

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.

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

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Just had the best buying experience! If you're in the market for a Lexus I highly recommend stopping by Bobby Rahal of Lancaster County and meeting with Cody Sofranek. I've been in the market for a car since July, and was beyond frustrated with the lack of communication and commitment given by sales people at other dealerships. The problems were vast. They were not concerned about my needs, not hearing back from them for weeks, and a lack of knowledge about the cars they were selling. All of that changed when Cody approached me in the lot. He made it clear from the beginning that he was not here to be pushy and was only here to answer questions and help. Cody was extremely knowledgeable about all three of the vehicles I was interested in. He helped me go through the pros and cons of each one for my lifestyle and needs. Cody definitely went above and beyond to help me get the vehicle I want, which is in high demand and hard to find (Lexus TX 350). He understood what a large financial investment this is, and let me take my time deciding what was going to be best for me. I truly felt Cody had my best interest in mind. He is knowledgeable and trustworthy, the two most important things in a salesman! After purchase, he spent time going over all of the technology in the vehicle. He also took time to mark pages in the manual he felt were important for me to review. He encouraged me to reach out with any other questions or concerns I come up with. All In all, I can honestly say I am so glad I decided to pull into Bobby Rahal that day! Cody Sofanek is a top notch, knowledgeable salesman.

Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

Everyone was great from start to finish. I think they identified the problem that other dealership I no longer go to couldn't. As of now no problems with my car

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 is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

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!

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.
