Used GMC Sierra 2500 trucks for sale near West Puente Valley, CA under $100,000

I live in Las Vegas. After being lowballed by multiple dealerships in Vegas, I decided to try my luck with selling my car privately. Omar from STG reached out and offered me the private party value for my vehicle, as a trade-in to STG. He said STG could pick the car up for a small fee or I could drive it down to their location in Montclair, CA. I was very hesitant on working with STG, as there are so many horror stories about crooked used car dealers. I felt I would be in a vulnerable position if I were to drive the car there and they were to lowball me. I decided the risk was worth it to me for the extra money, and I drove it down. Immediately, Danny greeted me and started the inspection process. I had been upfront and honest with them about small imperfections the vehicle had, so there were no surprises. After inspecting the car, Danny confirmed that they would purchase the vehicle from me for the previously agreed-upon price. This is a standup dealership with great customer service. I feel I was treated very fairly and I would absolutely recommend them to anyone looking to get top dollar when trading their vehicle. They even gave me a ride to the airport after the deal was completed. Thank you for making the process so easy!

Tom & Jerry in real life way better than the cartoon. Got me exactly what I wanted in a reasonable amount of time.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Dealer add ons are extremely high, we were able to work on some of those numbers. Still high after bargaining, but I agreed since I wanted this truck. When Mariah came back with financing option, I come to find out that we can't finance outside, it has to be their financing or pay cash! Can you believe this? After everything done with salesperson, had to wait for finance. Sat for over an hour &1/2. Employess kept walking in & out of finance office, some eating, while customer just waiting.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Staff was friendly but i left without being able to have my app hooked up to my car and I was looking forward to that feature

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

I had an amazing experience yesterday at Tustin GMC & Buick with Seth R.. I called him the night before to ask about the Sierra EV 2025, and he got right on it! We got the deal done in minutes, charged up the truck, and it was waiting for me to pick it up the next morning because I couldn?t make it that evening. This dealership is incredible! I usually buy luxury vehicles, and the service was just as great as when I do business with Porsche or Land Rover. George in finance was nothing short of amazing as well. The management is doing an incredible job keeping them going because they have such a great team. Every turn was met with a smile, and even in workout clothing, I felt like a valued customer. Thanks to Seth and George, this dealership is now my new pick-up truck home, and I?ll definitely be buying my pick-up trucks through Tustin GMC & Buick in the future.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

They doing the best, Joe and Pierre , helping me a lot, perfect choice, they have a great collection cars , the place is so clean , the cars so clean too,

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

Amazing service here. Bianca cashier great service. Thank you all for the amazing service here 🙏

Thank you David R, and Rene for your help getting my first car! Amazing experience!

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

I an very satisfied with my new Santa Fe. We stayed very long hours before everything was done but it was worth the wait. Our agent Juan V was very patient and really persuasive to have this deal. Thanks a lot to him and Hyundai Anaheim.

Overall was a great experience. No pressure, felt In control.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I went in to look for a car and the sales man was super kind and answered all my questions without the pressure of buying from them. I was treated like family and I highly recommended this dealership to anyone I know.

I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

Ok so I am sure my 1st review is not gonna be deleted but I have a new review for them as they have addressed my concerns and Because of 1 persons actions I am completely satisfied with the repairs and commitment that JOHN in service has made sure I was completely satisfied with the repairs so a big THANK YOU to John and anyone else who worked on this I will definitely be taking my truck back for service

Happy with my Porsche 911 Sales process went really smooth and fast. Big shout out to sales rep. Anthony for taking good care of me. He also delivered the car to my address at no charge. Only negative thing. The front brake pads needed immediate replacement. I believe if they measure 3-4 mm AutoNation won?t replace them. I found that to be pretty poor since it also illuminated the brake wear light on the dash. I was well aware but it wasn?t a deal breaker.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want
