Used GMC Sierra 1500 Denali for sale near El Monte, CA

GREAT BUYING EXPERIENCE, SALESMAN ANTONIO WAS GOOD AND FUN, HE TOOK MY BARBS AND KIDDING IN STRIDE. RONICE THE GAL THAT DOES THE PAPER WORK HAS A GREAT PERSONALITY, SHE COULD TAKE MY KIDDING AND FIRE BACK A COMEBACK, HAD A GREAT HANDSHAKE. ONLY PROBLEM, DOING THE PAPERWORK TOOK TOO LONG, I PRESUME BECAUSE QUITE A FEW CARS WERE SOLD THAT DAY

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

great customer service. facility was very clean. Parts department was very professional and informative on products. The service writer was very knowledgeable and very professional. They washed my vehicle which i was not expecting.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

once i arrived to the dealer, soon i have a personal attending my request, very profesional, always give them more options, always trying to get the best loan, im very satisfy with all the staff. make my experience one of the best

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!

In 2008, my folks bought a new Chrysler Pacifica Limited. The car sales man was great. He knew all about the car and showed us everything about it. The dealership it's self is beautiful and super clean. They also have AWESOME cars inside in which you can sit and mess around in. The overall rating is a 4 BECAUSE, it is so hard to get a hold of these guys to take the car in. We've called 4 or 5 times to only leave messages that have never been responded to, so we are planning on just going there whether they want us to or not!

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.

The service staff were friendly and efficient. My car was serviced (oil changed and tires rotated) and ready in a timely manner. The waiting area and rest room were clean

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.

Thanks to Denis! We just came to see the cars and check the price, and eventually left in a Ford F-150. Denis, you are an amazing manager who knows how not only to interest, but also to take into account all the preferences of the client. In addition, he also became our translator from English to Russian. Denis explained all the details, as a result, everything was clear and transparent to us in this transaction. Thank you, Denis, thanks to you, a working car has appeared in our family. And with the birth of the baby, it became very convenient and more comfortable to have 2 cars in the family. Denis, we wish you great sales, profitable deals and only super customers.

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...

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.

Pretty great experience overall. My sales representatives Maria and Rene were very helpful, answered all my questions and made the whole transaction quick. Highly recommend STG Auto!

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!

Bought a certified 2015 BMW 535. Ultra clean and low miles. Smooth transaction. Fair value for my trade in. Overall very pleased with staff and process.

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.

Great service Jay is my guy at the service department always takes care of me I never need to worry about my truck I know it?s in good hands

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.

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

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

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 just want to say that Jorge was so patient with me during the whole process and smiling all the time and even offered me lunch which is very rare these days he's really really nice and very good at his job. I dont have enough word to thank Jorge seriously And Mina the manager was professional as well very nice we had chat after i closed the deal very nice man gave me a lot of advices about cars that no one did before If you guys go u won’t regret it at all They will make sure to give u the best value in the market for ur car if u trade in or sell an give u good deal on their cars Dont look around if u want to buy a cat Best team best manager hands down ill buy my next car with you guys for sure ASK FOR MINA AND JORGE ✌️✌️👍👍

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.

My truck was service and clean in the time promised. The service advisor are allows courtesy and helpful. The dealership and waiting area is clean and easy to assets

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

Love this place , love the service, love how fast my process was to get into my M4 .best dealer I’ve ever made business, super polite , humble and very respectful, they even car washed the vehicle, man come one I was like whatttt!!! Super happy I drove out from Hollywood and I was not disappointed. Check it out for yourself!!!!!!

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Tuve una buena experiencia en esta tienda me explicaron cada paso hasta asegurar que había comprendido Rolando y Carolina me ayudaron mucho
