Used GMC Sierra 1500 trucks for sale near Upper Mahantongo, PA under $899,990

They have been so helpful past and present with the services on my jeep!! Easy scheduling and love the reminders. All service personal are pleasant and helpful.

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!

Their customer service is excellent, waiting rooms are always clean and have snacks and WiFi, technicians are knowledgeable, and labor and part prices are always fair.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Shawn Z was extremely helpful patient during the whole process. We have worked with him on vehicle purchases in the past as well and will continue to use him and this dealership on future purchases.

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.

We worked with Mike Briseno and he was excellent! He worked to get us the best value for our trade-in and worked to get us the pricing on our new vehicle. I highly recommend Mike and try folks at Frederick!

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!

Got online seen the truck said I was interested got the phone call from the salesman had everything all set up for me to come drive and sign in and out in less than an hour.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

this is the first time in all the years I have my vehicle that when I got my oil change I did not have to add oil. Everytime before this I had to add oil a day or two later. Who ever did the oil change was great. Thanks

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

I had been looking for a pre-owned car online for some time. Found a car at Frederick I was interested in getting more information about a possible purchase. Cody was very helpful when I arrived at the dealership. Cody was very helpful getting the information that I needed to make the decision. I really appreciated the straightforward process. I was able to purchase and drive the vehicle home the same evening.

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

Best sales transaction ever with Cameron Watson. No bull, no back and forth and honored a mistake of an online price error. In and out with truck in shortest time ever!!

Dave was an excellent sales person to deal with, the entire process was seamless! Great communication on all aspects of the deal. I would definitely buy from him and Alexander GMC again.

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.

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.

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

Good service from both Parts (purchased an item for our vehicle) & Service Depts (who took me in without delay.
