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

Courtney and Wes were great to work with. They both made our purchase easy and painless! We will definitely be back at Thornton for all service and maintenance on our vehicle.

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!

Moo Jim Addlesberger and Danielle were great to deal with while purchasing our newer car. Good experience all the way around. If you’re looking for a friendly, fair person in looking for your next car, look no further than Jim.

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 had a oil change and transmission check. The work was done quickly. The service lane assistant Alli Smith was very professional.All work was done well.

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

Outstanding service all around ! Immediate availability and quick completion of service! Satisfaction guaranteed! 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!

just purchased 2019 silverado from JOELWATSON GREAT delivery experience very thorough on all features AND all options

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?

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.

I was shopping for a very specific Corvette convertible and found a 2006 available at South Street Autos. Since I am from central New Jersey and was facing a 3 hour 25 minute drive to Maryland(according to Mapquest), each way, I called hoping to get some information about the car that was not listed on the website. Wayne was extremely helpful and courteous on the phone, answering all my questions. Most cars look great on the internet and then you get there and it's not what you expected or hoped for. Wayne and John were totally upfront and honest about the car. They were very understanding of how far away I was and were kind enough to pre-negotiate the price on the phone (most dealers would not do this) and provide me with an "out the door" price so that all I had to do was make the drive there and hope it was everything they said it was. Well, I made the trip and it was as beautiful in person as it looked online and was EXACTLY as they had described it. Because we worked out a price that was fair to everyone and the car was what I was "sold" on the phone, I bought the car on the spot and am thrilled with my purchase and the quality of the car. I would definitely make the 6-7 hour round trip again to buy a car from them, it was well worth it! Thank you for your honesty and fairness!

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

I Purchased a 2015 Tacoma TRD PRO on line. I'm 3 1/2 hours away so everything was phone and email. Couldn't have been an easier process. I was sent a video walk around of the truck and the manager pointed out every little rock chip or imperfection. From Wes the Manager to Brian in Finance to Ryan in Sales...Top Notch! I'm like a lot of people that don't like dealing with a car dealer...I've had bad experiences in the past. This was the smoothest, easiest transaction I've ever had at a dealership. The truck was priced fairly and when the shipper delivered it, the condition was exactly as I was told, No Surprises! I would buy from these guys again in a heartbeat. It's nice to deal with responsive people that shoot straight and do what they tell you they will do! Great Job Thornton Automotive.

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.

Service was excellent and the did everything exactly as they said the would! Very easy process!

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 found the exact vehicle I’d been searching for online. It was not in my home state which made me nervous but I contacted them any way. Brady made my buying experience effortless, smooth & easy. Best of all, no pressure. Everything was done for me. From contacting my credit union, giving me a good price on my trade in & registration in my home state. I was able to leave with my new car that day. I didn’t think that was possible but the folks at Len Stoler made it happen! I would make the trip to buy from them again.

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!

My husband and I stopped by Awesome Autos Saturday evening before they closed. My credit had taken a little hit from covid. I had a couple vehicles in mind. They happened to have what I was looking for on the lot. Kia Soul, with a manual transmission. We were greeted by Ryan and had a wonderful experience. The staff along with Ryan helped obtain a payment below what we were anticipating. Go see Ryan and staff at Awesome Autos

Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

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.

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 purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Dave G. was very helpful and kind. We appreciate everything he has done for us!

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.

Came in looking for a vehicle had a vehicle in mind took SUV for test drive went through the process and came home with it very pleased with SUV and the way I was treated would highly recommend Fitzgerald to anyone

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. ??????????????????????????????????????????? ?????????????

We recently traded in a truck and purchased a new one here. Erik P was extremely helpful and knowledgeable while we were exploring trucks. Erik took the time and genuinely wanted what was best for us and not just to make a sale!! Ask for him when you go!!

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!!

Great overall experience. Clear and transparent sales team. The process was quick and easy, would highly recommed.

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
