Used GMC trucks for sale near Highland, CA

We've had only the best service with Diamond Hills. Everyone we have come in contact with over the last 2 years has been pleasant, courteous and helpful.

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. :)

Always well taken care of by Dan in the service department. He is honest and transparent about services needed for my car. Been going to him for years and trust his opinion. He feels like part of the family! Thank you for being you Dan! Always amazing

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.

Kayla the service rep was so nice! My first service on my new car was so fast and they even washed it! 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.

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.

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

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!

As a woman making a vehicle purchase, I felt comfortable and not pressured. Edgar in the finance department was very helpful and made sure I understood all aspects of the contract.

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.

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!

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.

Megan helped me and was fantastic. She explained everything and made the buying process a great experience. They were fast and didn't try to oversell me on warranties or options.

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 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!

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

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 came looking for a couple of trucks for my business and i found exactly what i was looking for i bought three units for my business i would have almost double the amount if i would have bought new...they allowed me to take the vehicles out to the franchise dealer and some things needed to be fixed so they took care of those little details got me commercial financing and i was pretty much on my way I recommend this dealer no doubt they have a huge inventory you just have to do your own due diligence...

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Really Happy with my experience here with the dealership. Tom was my salesman and worked very hard to get this deal for me. Kept in touch with me, and worked very hard to get my loan approval! Definitely would recommend!

Keshan and Hamsa were Great through the whole process fast and quick will definitely buy again

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

In September 2023, I purchased a 2023 Jeep Compass from this dealership, and I have been treated with the utmost respect from everyone that I have ever dealt with. I have dealt with several dealerships throughout my life, and I must say that this dealership location has some of the best people that I have ever dealt with. The professionalism and kindness I have experienced from everyone there have been nothing short of exceptional. This includes the sales personnel, the finance department, and the service department. I would highly recommend this dealership to anyone looking to purchase a new vehicle. I would also like to specially thank Roger Martinez, Denise Ennen, and Diego Rivera in the service department for always giving me top-notch service!

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Adam did a nice job locating the vehicle I wanted to see. He went the extra mile tracking down the service manager, beginning the purchasing process, and ultimately ensuring the vehicle was ready for pick-up a week later. I found Adam to genuinely care that I had a good purchasing experience.

I want to start off with the compassion this place has for the customers. I never once felt pressured for anything when being here and talking with the sales reps. I had the pleasure of doing business with Rami. He took things at my pace, was very understanding and I felt tried his hardest to get me into the car I so desperately wanted. He kept me updated on the car and walked me through each step making sure I was comfortable and answering my questions to reassure me of what was going on. Then came the gorgeous Vanessa who emailed me during the week to make sure my dream car was still available. When I went into the dealership she introduced herself and sat to talk to me even though I was working with Rami. She was very nice and also made my experience that much better. She honestly cared and I could tell by how passionately she spoke to me and could see it in her eyes. Last came Argenis who tried his hardest to get me the best deal I could handle. He was very professional and walked me through everything. He made the experience very comfortable and I am very pleased with my whole experience here. I would recommend 10/10. My best experience by far with any auto group.

I didn't have an appt but they were awesome anyways. But nothing breaks on a schedule lol. I was helped quickly, offered coffee and a seat. They kept me updated on the car and how long it'd take for the parts. Thx guys, great job as usual.

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.

This is my second Lexus purchase from Crown Lexus. It was a pleasure walking in to this sparkling clean showroom for my appointment to look at pre owned cars and have my trade-in evaluated. I was greeted right away and we began the process. Abel listened to my needs/wants the entire time and we worked through decisions leading to all the paperwork and then with the accounting specialists to finish the process. Attention to detail all the way. I appreciated everyone involved.

So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

I hade a Great experience at this dealership , Thank you Dylan for makeing my dreams come true. and to the finance depatment Freddy who made it very easy and fast, Icould not of had a better experience. I truly recommened Diamond Chevrolet Banning.
