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

Bought a 2022 Santa Fe from Alec Deese. My Wife and I were looing for one and Alec sent us a message that one had come in to the dealership and we went to look at it. Took a ride in it and car rode very nice and was very clean. We bought it. Alex was very helpfull in getting the car. We would recommend Jack Giambalvo Hyundai and Alec to anyone looking for a good car. Thank you.

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.

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.

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!

Purchased a 2017 Acadia Denali, Everyone I worked with did everything they could to accommodate my request. There was absolutely no pressure to by the automobile. Great place to do business.

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.

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

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!

Ron Kessler is absolutely amazing! He genuinely cares about his customers and always does what’s best for them. I never have any worries when I know Ron is fixing my car. All staff at Thornton are always super kind and welcoming! Hunter was especially kind and helpful!

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 drove all the way from Charlotte, NC to buy a beautiful Alpine White BMW 328d touring M-Sport. These guys already had the car on ready for my test drive when I got there. It was missing the floor mats and I was ok with it but they offered to ship me some new OEM rubber ones! I work with dealerships for a living, these guys have hands down some of the best customer service I’ve seen. They also worked with my local FCU even though they’re not in PA. Thanks guys!

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.

*PAINLESS Transaction* Sam & his staff @ Lime Ridge Auto are Top Notch!! Looking to buy or sell your diesel truck this is the place to go. Don't go shopping for a diesel truck without stopping by Lime Ridge Auto!!! They make dreams come true!!!

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...

Kevin Bacon is reliable and trustworthy. I depend on his expertise for my 2006 Buick Lucerne to operate safely, reliably and efficiently.

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.

Brian was great to work with no pressure to buy, Told him what i wanted and he was great at making it happen, He wants me to call if any problems so that we are happy, Paper work was quick and painless, Love my new Yukon Denali,

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 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 did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

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.

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.

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

Fantastic dealership, my sales person was Matt . Saw my 2006 Ram on line with 91,000 on it for such a low price I thought this must be a mistake. Drive up from Delaware picked up a friend and drove over to Morgan’s i’m not kidding when I say this truck looks like it was in the show room beautiful I could not believe it if it wouldn’t of been for the year I would’ve said this truck was brand new they even put new tires on save me a lot of money there would highly recommend this place to anyone that’s looking for a good used car no hassle no hidden fees straight up sales people thank you thank you thank you.

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.

Recently I took my 2011 terrain back for repairs for the 2nd time. After facing a bill of $492.00 Mr. Bacon understood my problem and told me "don't worry , the parts are on the way and your window will be fixed. He later told me that they want me to pay $100.00. I told him my 1st visit was within my warranty and I shouldn't even have a bill. Later he came back and told me "you're good". I thanked him for his services. I will call Mr. Bacon for future services.

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

The salesmen and the people there we're excellent, but unfortunately the car it was not in good enough shape that I could purchase it. It wouldn't pass inspection

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

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.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

I was looking for a slightly used Jeep Wrangler. I've seen Auto Connection and the sweet vehicles they had. Through an acquaintance, I was hooked up with Jeremy Horst who helped me trick out my new Jeep. I started with a base model 2018 Wrangler Unlimited Sahara JL—I was able to pick out my wheels and then Jeremy guided me with what lift and tires I should add. The entire process was seamless and was actually fun and exciting! Jeremy delivered on his word—a gorgeous Jeep! Thank you Jeremy for all your help and guidance. I would recommend Jeremy and Auto Connection if you are looking for a sweet ride!

This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

He was very polite and he let me test drive the car now I have to get financing. I really would like to own this car. But first he'll have to show me all the functioning of the car
