Used GMC Sierra 1500 SLT for sale near Altadena, CA

My salesman was Mason. He is new to car sales and I had the privilege of being his first sale. He was very attentive. Didn't pressure me at all. Took time to help me find what I needed. Me being a single mom, his manager Julio understood my budget and circumstance. Everyone was great. I'll tell all my friends about them.

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

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.

Recently I had to get a newer car and believe me I was stressed because of the situation but when I went to CarMax which this is my second car from them it was once again amazing to work with them! I had the pleasure of working with 2 amazing sales associates. Helen Mayo who was my main sales associate and Cheyeene Toliver who helped out my wife and myself when Helen was off! They both were very kind and helpful and made the process an ease! I was thinking of other options but since they were amazing I went with them instead if your looking for a car I highly recommend you ask for either of these two women they are a great help!

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

This was the easiest purchase of a car that I've ever had! No haggling-just bought it! They bought mine and then I came back and bought one from them

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

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

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’ve had a fantastic experience with this dealership. I’ve purchased four vehicles from them, and each one has been great. The person who helped us this time was Dj, and he was exceptional from the moment we met. The car is beautiful, and I’ve never had any issues with any of the cars I’ve purchased here. The customer service is always amazing.

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.

Leo at Pro X motors was amazing. I got a very good deal on a decent 2016 X3. Leo was a pleasure to work with, worked hard to get the deal done and I left with the car I wanted for a very good price. I would recommend Pro X Motors to anyone looking for a competitively pre-owned vehicle. Thank you very much!!

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Arman was amazing to work with. I bought the truck without seeing it person and he provided accurate information. He was very patient and easy to work with. Absolutely no pressure to purchase. The vehicle was quickly shipped across the country and arrived as represented. I am very happy with the purchase and would strongly recommend this dealer to anyone looking for a used vehicle.

I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

This was one of the best experiences I had purchasing a vehicle everyone was kind a very knowledgeable. This was the quickest I've ever purchased a car thank u !!!

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.

The experience here at Car Castle was by far the Best car buying experience my wife and i have ever had. Thank you Eddie the (Manager) for helping and assisting us with the whole buying process and for giving us a Great Deal!

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...

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Had great experience at Metro Nissan. They made the whole process easy. My salesman Rudy and he was very helpful. Never felt pressured or rush. Thank you Rudy for my new Rogue!!

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.

Personalized experience with a smile. Everyone was great, and helped get me out of a car I didn’t like and into a car that I wanted. Thank you Envision Ford of Duarte!

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. :)

THE CAR I"M LOOKING AT IS STATE OF CALIFORNIA AND I WAS ALSO TOLD THE CAR WAS ON HOLD FOR ANOTHER BUYER. HOWEVER I REALLY LIKE THE CAR.

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

Lisa was great very helpful approachable friendly had a sense of urgency. Got things squared away very fastly. Overall great experience at Chevy of Carson.

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.

Great cars , at an even better price ! Juan was great, got me in and out in no time in my dream car.

The truck Handel's well. Sluggish when in second gear and the transmission thumps mostly when shifting down. Started about 40k. The ride is nice and comfy.

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

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

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!

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

The telephone call was pleasant. The sales person was cordial, and informative. Our problem was she is on the West coast, and I am on the East coast! It's, as you might expect, difficult to buy something sight unseen.

I really like my nw, to me, 2015 GMC Sierra Denali. The salesman, Terrance Lin was very efficient, helpful and courteous. Thank you very much.

Very excellent professional experience with Jose our salesman. Owner very nice personable guy Dealership 5 star

It met all of my needs, it drives well and is easy to maneuver for its size. I would recommend this vehicle for anybody who needs a full-size vehicle.
