Used GMC trucks for sale near Antioch, CA

Overall great experience. The guys take care of me like they always do in making it an easy and seamless experience. I recommend anyone and everyone buy a car from them.

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.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Mike took care of the issue that my truck was having and I was back on the road the next day

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 loved the no hassle and great price on warranties. I would recommend CarMax to everyone.

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

The service was amazing! Stone was amazing and made the buying process easy and fun! Everyone was very nice and seemed to truly cared about us.

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.

Simon he always take care my truck for me, he is excellent.

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 !

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. :)

I would give them 10 stars if I could. I have purchased 2 vehicles from this location and have my entire family shopping here! Great service and follow up! Great used cars here! My family and I will shop for out vehicles here from now on!

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 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

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!!

Great customer service, over all wonderful experience! Tyler and Reza were extremely helpful and patient. Would most definitely buy a car from here again.

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?

Great buying experience never felt pressure they took my budget seriously and worked to get me what I asked for. I would buy from here again and I think I will for my next car and will recommend to anyone looking to purchase a car.

Awesome service . Quick, easy, safe and professional. I would use this service again in the future.

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

Although i never made it in to test drive, the sales rep and online sales rep were very helpful in answering all my questions.

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

Sales person Diego was excellent and explained everything very thoroughly but the car didn’t meet our needs

Great service and follow up. I would highly recommend the dealership if you were looking to buy a BMW in the near future.

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.

The dealership is very pro-active when servicing my vehicle. I appreciate their detailed & full vehicle inspection which spots & corrects minor issues before they become major problems.

I had a great car buying experience. I would definitely come back. The team was very helpful and made the experience a good one. I highly recommend this car max location and the people who work there.

Had my 2024 Canyon for exactly one year. Not a single real issue once over the air update was done and that only affected the radio. It was an AT4 in desert sand metallic. I traded it for a 2025 Acadia, as I missed life in an SUV. However if you want a truck, I’d highly recommend it and specifically the AT4 model. It’s got meaty tires for pothole protection, it’s able to tow more than you can imagine, it looks super amazing and you’ll have lots of thumbs up and positive comments when you get gas, etc. updated tech was more than you could ask for. 4WD auto mode worked flawlessly. Engine had a nice little growl that I miss too. Let me say if you are a truck person or want to be a truck person, it’s a perfect mid size truck. Mine was 100% and am missing it yes but love the Acadia because it’s also a great vehicle. Got the AT4 Acadia and for my situation it’s perfect.

With a 5.3 L 4x4, Z71 and tow package has been an excellent truck. Options include a locker deferential. Used to tow a 21' Camper and does a good job of handling the tow. Milage while towing is only 11 MPG (expected with a V8 and a 4.10 rear axle) now with 125,000 miles. Like the torsion bar Front suspension, quiet smooth highway traveling. Moves VERY well in traffic. Does have a large turning radial for a small pick-up. I have used the truck to pull Compact Tractors and other items out of tough spots with ease. (4x4 low setting) No transmission issues, Truck serviced at regular intervals, all fluid gear train lubricant and coolant changes. 4 speed transmission fluid at 30,000 mile and engine oil at 5,000 mile intervals. Engine has had no issues, runs and idles smoothly.
