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

I had an outstanding experience with the sales team at Tustin Ford. From start to finish, they were incredibly patient with me and my busy schedule, never making me feel rushed or pressured. They took the time to truly understand what I needed in a vehicle and made sure every option they presented aligned with my priorities. What stood out most was how far above and beyond they went throughout the entire process. Their professionalism, communication, and genuine care made this one of the smoothest and most enjoyable car?buying experiences I?ve ever had. I left with a vehicle I absolutely love, and I owe that entirely to their dedication and expertise. I am now ? and will continue to be ? a proud supporter of Tustin Ford?s staff. They?ve earned my trust, my loyalty, and my highest recommendation.

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.

Best car buying experience I've ever had! They went out of their way to serve us and our needs. Teresa even went out of her way to bring a car I was interested in from a sister dealership so I could test drive it that day. Crown Lexus is what it means to work as a team and to make a personal connection with their customers.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

First time buyer 12/12/2024 ..JP was able to help me with all my questions and needs to purchase my new sierra pro ..thank you JP you're awesome

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.

Only trust them with our baby. Videos of our car explaining need repairs showed us everything Custom service second to none Friendly staff Good coffee

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 !

This was the second car we bought from AJ and as usual his service was amazing! We highly recommend this dealership and his service!

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.

I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.

Overall, I had a good experience purchasing my vehicle here. Thank you to Wes for being so kind & helpful!

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.

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

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. :)

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!

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.

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

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!

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

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?

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.

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

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.

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.

I worked with salesman Travis and he walked me through the whole process with no pressure. He is definitely an expert on Raptors and let me know everything about it. I will definitely be enjoying my Raptor out of in Jurassic Park aka 405 fwy

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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.

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!

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.

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

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

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!!

I did not have the pleasure of purchasing the Accord Hybrid at the dealership. In fact I am waiting for my car. My purchase was not made their due to the convenience of driving down the street to my credit union where my car will be delivered.I wanted to commend the customer service that salesperson Jun provided. He was attentive to my needs and wanted to work with us in purchasing the car there. He followed up with me via text and went the extra mile to get me the car. Anyone living south county and wants to purchase a Honda should go there..

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.
