Used GMC Sierra 1500 trucks for sale near Diamond Bar, 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 !

Worry free experience, Bobby the service staff/mgr is very nice and friendly, explained well the process, the work done and condition of my vehicle thank you Autonation

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!

J Star Dodge has the best customer service of any place of business I frequent. They have been the only place I use to service my 2019 Dodge Durango. I have 69,200 miles and it runs like it’s brand new.

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.

Just bought my car from Carmax in Costa Mesa. Michael helped me. The whole experience was easy and painless. It really is the way car buying should be! When it's time for me to buy a car again I'm definitely going back to Carmax!

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.

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!

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...

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

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.

Good job, Great service, thank you. I will alway bring my car here

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

I cannot recommend Eddie Aguilar at California Motors Direct enough! If you want a salesperson who is terrifically professional and truly on your side, this is the guy. We drove through two counties and fought a ton of traffic to make this deal happen, and Eddie was more than patient with our schedule. What really blew us away was that he and his manager stayed late just to ensure we left that night with the car we deserved. It felt like "NO" wasn't even in his work vocabulary—he ground out the details and made the numbers work perfectly for both the lender and me. The BMW i4 is running beautifully, and you weren't lying when you said I paid below market price! My girlfriend was so impressed by how sincerely genuine the excellent service was that she is already planning to come back to CMD to purchase her next vehicle. Facts. Cheers fellas!

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

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.

I found the car I wanted at this location and they were super helpful in getting it transferred FREE to a location closer to me so I can go in to pick up.

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.

Excellent job for regular maintenance of my car. The service desk knew exactly what was needed and explain the nature and time frame. I was asked if I would like a complimentary car wash which was great. In the past I did not know if this was standard. It was nice to be asked.

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 whole staff, sales and service are friendly, helpful and honest to deal with. They take care of your needs.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Aaron has been very courteous and professional during my contact with the dealership. He's gone above and beyond in his approach to customer service.

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

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.

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!

bought my Chrysler Voyager from Sterling Imports, i went to many dealerships but they judged me because i came in with a bicycle and only $500 cash, these guys took a chance on me and gave me and gave me an opportunity to turn my life around. I call them my Angels because they helped me so much.

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.

We had our oil changed on my 2018 suburban. Our service writer was Faith. She was very informative. She checked us in and reminded us of our Chevrolet rewards point. This is the first time anyone has asked us if we wanted to us our rewards. We have been having our work done at George Chevrolet since we purchased our suburban. I really appreciated Faith,s effiecency and keeping us informed during our visit. We will make sure we ask for her on our next visit.

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.

Our salesmen, Miguel and Oscar were very helpful as we went thru this car-buying process, Miguel even helped me set up my bluetooth before I left for home .......... I would recommend Car Max- this is our 2nd vehicle purchase at this location.

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

We bought a car here today. Jafar the manager was great. He did not pressure us into anything. He let us take our time to decide which car was best for us. No haggling just like the ad says. No hidden fees is a plus in my books. All in All a good buying experience.

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.
