Used GMC Sierra 1500 trucks for sale near Porter, OK under $899,990

I recently had service at Mark Allen Chevrolet (formerly Mark Allen Chevrolet) and was very impressed with their team, especially the service department. They met all my needs and exceeded my expectations. I needed new tires, and my service technician went above and beyond to find the best price and deal. Thank you for the exceptional work you do.

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.

man i showed up nervous scared because buying a car is scary! But Ryan Ortiz showed me how easy car buying good be and it felt like a had a vip experience with ryan!!

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!

Got same day appointment. Was in and out quickly. Neal King is always very helpful and fixed an issue with my Bluetooth.

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

It was a great experience. They was very professional He is very knowledgeable about the car and the whole experience went smooth and we’re very happy with it and we love our car

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

It was a pleasure working with Shawna in the Service department. She's the best!

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.

This dealership is fantastic. Addressed an issue I had and made me 100% happy with purchase. Will buy my next truck here!!! I drive from okc to Tulsa in an Uber to deal with these guys! Glad I did.

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

I have never met a sales crew that worked so hard to meet our needs. We had challenges in our credit & yet they were able to get us financed with down payment & terms acceptable to us. Our sales person Brayden was the best. He made us feel comfortable & he was very professional. I will definitely be a repeat customer & will request Brayden’s help when we do. The dealership was clean, had great snacks & very comfortable lounge area. A wonderful experience. Thank you Patriot & Thank you Brayden

The were responsive and communicated well without pressuring me- As a non-local shopper, I felt like the customer service was really good.

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!

Great people David Howell service advisor goes above and beyond helping his people to get what they need

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.

Great and fast service. First time I had been to this location. Very impressed with the service department. You will have my business from now on.

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 bought an Envision from Wyatt about a year ago! Great service and True Pricing! This young man was Honest and true to his word!

I loved the experience I had here. Everyone was so nice, very clean, haste free environment

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!

First time buyer and was extremely impressed with the professionalism demonstrated. Tyler , my sales person is very responsive to questions and concerns and was extremely helpful throughout the process. Cory the sales manager was very helpful as well assisting with his expertise. I’ve returned several times since purchasing Dec 30 2023 and he always takes time to make sure I’m happy with my purchase. Jason , the finance manager was absolutely a pleasure meeting and so helpful in securing a warranty and financing. I left feeling like we had known each other for years. Great guys who want to earn your business for sure

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.

Bought a Lexus ES 350 40k miles, four years ago. Great buying experience. No hassle. Got me in and out with financing. The paint job, front bumper went south on me about 6 weeks in. Not carmax's fault. Lexus had a problem with paint on that year make and model. Purchased a warranty. Best decision made in a long time. Very reliable car, extremely reliable warranty. During the last six years, the warranty has paid for about 7k in repairs.

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

I was contacted by my service advisor Geoff with an update on the progress of my vehicle. He was also able to get me a loaner vehicle which was very much appreciated. I was provided daily updates also which helped me through the experience I was dealing with. I have been contacted that my vehicle is completed at this time and headed over to pick it up today. Great day. I would like to Thank my service advisor Geoff for keeping informed and going above and beyond to ensure my experience was pleasant. You'll be lucky if you get Geoff as a service advisor.

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.

I found the truck online and LaSha was very helpful in the buying process. I got a fair price on the truck and my trade, and overall I had a great experience buying.

I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

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?

Lane was a great salesman, got what we wanted and was out of there in no time!! There was no pressure we just told him what we wanted and that is what we got!! Awesome

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Had an amazing experience with this dealership! Zack was very helpful and friendly! He helped me finance my first car! It was a very welcoming environment and made me feel comfortable! I would definitely recommend!

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.
