Used 2023 GMC Sierra 1500 trucks for sale near Rancho Cucamonga, CA

Great experience. Simple and easy. Great staff. Definitely would recommend.

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!

This is a Ford dealership and not a Lincoln one persae. But the level of service they offer to the Lincoln owners are over and beyond any Lincoln dealership we have been for the decade. The service, the skill set of its technicians and the degree of care they offer to the Lincoln owners are truly a unique and memorable experience. We dropped our car for a typical oil change. However after due diligence, there was a recall and few other items that should have been noted and taken care of by the Lincoln dealership that we used to visit for years. None were noticed or taken care of. Here, as a courtesy, that service Lincoln, but we felt a huge difference in the car runing before and after the service here. HUGE! Chad, the GM is the most pleasant and service oriented individual you will meet here.

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.

Although the car we wanted didnt work out, the customer service was excellent. MARCUS is a STAR! He should be in management. I have brought many mercedes in the past. Carmax is turning the tide when it comes to purchasing vehicles. The best thing to do when you buy any car is to take it to another mechanic, and then bring it back to the place to be fixed within the warranty period. The Truck I purchased from them a year ago had a few issues but they did take care of it and I've not have any problems since. Carmax has set the bar high for purchasing returning and anything to do with cars. BRAVO!

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.

I always take my vehicles to Selman Chevrolet for service. They do great work and Todd Kalmen the service representative is outstanding.

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 had an excellent experience all staff very helpful and friendly. It's was the best experience we've had at a dealership. They are so straight and transparent about everything we've asked. By far they exeded our expectations.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

Amazing service! Caring and attentive to my auto requests. Chris was a tremendous help. He was so patient and kind. Go get a car from STG! I have nothing but good things to say about my experience

It was a great experience and Dom was the best! We will definitely come back for our next purchase.

Salesman Trey made the process easy and fast. I gave him the criteria I was looking for and he delivered even with my not so great credit. No hassle and no xx that I have gotten at other dealers.

Dominique is very good customer service in my buying today for the Ram 2500 working with him was very easy

Randy at STG auto was amazing and professional. He was able to work with me to get the rate I want and super satisfied. Highly recommended!

I had an excellent experience! The staff here are absolutely wonderful—friendly, attentive, and always willing to go the extra mile to ensure a positive experience. Their professionalism and warm demeanor made my visit truly enjoyable. Highly recommend!

We were happy with the service and time it took to complete our purchase. A sales rep (Jerry) worked with us over the phone and had many documents ready to go and prior to our arrival.

I want to start off with the compassion this place has for the customers. I never once felt pressured for anything when being here and talking with the sales reps. I had the pleasure of doing business with Rami. He took things at my pace, was very understanding and I felt tried his hardest to get me into the car I so desperately wanted. He kept me updated on the car and walked me through each step making sure I was comfortable and answering my questions to reassure me of what was going on. Then came the gorgeous Vanessa who emailed me during the week to make sure my dream car was still available. When I went into the dealership she introduced herself and sat to talk to me even though I was working with Rami. She was very nice and also made my experience that much better. She honestly cared and I could tell by how passionately she spoke to me and could see it in her eyes. Last came Argenis who tried his hardest to get me the best deal I could handle. He was very professional and walked me through everything. He made the experience very comfortable and I am very pleased with my whole experience here. I would recommend 10/10. My best experience by far with any auto group.

Not happy with the degree of energy some employees/ sales people were and most likely won’t come back or recommended Although Dom Was excellent With his communication and care He was one of the only one here with people skills

Randy was solid, he helped me & my friend the car we wanted. We got a good price and overall the service was excellent there. I would highly recommend coming here for a used car !

Mark Christopher GMC is an amazing Auto dealership. No sales pressure and terrible prices. Johnathon Villa was an outstanding salesman that helped us get a 2022 Canyon Elevation. He took extra steps to help us find the perfect truck for us. We drove over an hour. And so glad we did. Highly recommend. And I want to say thanks again to Johnathon for making the experience great.

Carlos was very helpful and patient with us. He showed sincerity and honesty in his work and towards us. Overall, it was a great experience buying a car in this dealership.

Abraham was great he is the sales manager there that helped me get a great deal I was scared because I’m a first time buyer but he made the process smooth thank you

Keshan and Hamsa were Great through the whole process fast and quick will definitely buy again
