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

Had an unexpected great experience in the service department today. Thank you to Javier for all his help. Will continue to come ask for him when I take in my new Maxima.

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 !

A big thank you to the guys at J Star. From Jace helping us on the sales side to Chris in Finance. I would recommend J Star to anyone! Thank you.

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 purchased a used Mercedes-Benz E55 AMG from the Carmax in Costa Mesa, CA about a month ago. I started out by calling the Carmax and reaching a sales agent. She worked with me by setting aside the car so that I could fly down to pick it up. She picked me up from the airport about 15 miles away from their dealership. When I saw the car, I found some minor cosmetic issues with the car and Carmax assured me that they would repair them at my local Carmax in Roseville, CA. I will be writing a review about that Carmax as well. They issued me a form stating repairs to be done at my local dealership. I informed the salesperson that I would be pushing the car a bit and she was fine with it. After the test drive, the car seemed to be in great condition, so we headed in for the paperwork. The appearance inside of the dealership building did not convey a welcoming feeling though. It felt like a warehouse with desks in it. The people within the building were nice and friendly though. The paperwork was pretty quick as I already had a loan check from the credit union. It took about 30 minutes and then I was on my way. Overall, I would say the experience was positive.

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!

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.

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

Anthony sold me the 2020 Mazda 6. Super nice and very informative and fast too.

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.

Es exelete lugar para comprar carros buen servicio y buenos precios sin duda el mejor lo recomiemdo siempre a todos deberian de ingresar es buen lugar

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.

sale associates very helpful during whole process. very pleased with purchase and customer service. Second auto bought from carmax.

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 do all my service here. They are friendly, knowledgeable, and helpful with coupon savings, too.

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 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

The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

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

The experience was Great! Mr Lozano is a great salesman, he helped me with all my questions, all the process was very smooth and simple, all the team is great from Lozano, Tony and Yuri great people, I?ll comeback to do more business with them

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!

These guys are the best in the business, honest and transparent will definitely be coming back and recommend my friends and family. Good selection of cars to choose from.

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.

Best advisor Louie in the Service Department. We were promised a same day service and it was completed as promised. In addition, this dealership always delivers the best service.

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.

I bought a 2004 Pilot a month ago here. My salesman, Tim, knew exactly which loan to submit me for because I had no job and bad credit but a big down payment. He had me financed with no problem in minutes. A few days before I went to Carmax Burbank for a different car but with the same down payment and the saleswoman there did not do the same thing. The car was purchased in 2 hours and I was driving home. I bought the warranty tey offer which is a great bumper to bumper extended through their company. They have a 5 day return policy. I opted to return my car on day 4 to pay for the warranty in cash so as not to finance it at the very high interest rate I bought the car at. The return was also easy and everything was done in less than an hour. A month later now, I have found a few things wrong with this 2004 that seemed to have slipped past their extensive reconditioning program. I took it in with odd complaints a dealer would normally say they couldn't duplicate. They addressed them all and even gave me a loaner SUV for my babies to fit in while I waited the few days for the parts to arrive. GREAT STORE! Great customer service! And there's a play room for the kids! *Avoid the coffee!! It is terrible!!!

Dealer ship sounds good, have not personally gone to find out for my self yet. But when I’m ready I will go take a look

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

I was running late past there closing time. They were very gracious and waited for us. Very nice to do business with.

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.

the process was so easy and straight forward. Nothing was hidden. Purchase process was beyond my expectation. So far, vehicle is running great !

I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.
