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

Great service Jay is my guy at the service department always takes care of me I never need to worry about my truck I know it?s in good hands

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!

Christian and Rob were the absolute best to work with at Walter’s Mercedes Riverside. They are very professional, honest and straightforward. So happy with our new purchase and the entire process.

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

Mazen was awesome! He was very helpful and made the whole process very smooth. We were trying to figure out what choices we had, and Mazen narrowed it down for us especially since we have a family that is continuously growing. Excellent customer service and amazing overall experience. Thank you again, Mazen!

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. :)

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.

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.

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.

Personalized experience with a smile. Everyone was great, and helped get me out of a car I didn’t like and into a car that I wanted. Thank you Envision Ford of Duarte!

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 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 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.

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.

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!

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.

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.

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!

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 have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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

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

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.

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.

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...

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.

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.

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.

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?

Cars Unlimited of Santa Ana may seem like your average used car dealership as you drive by. The reviews are a hit or miss online and you really don't know what to believe. My three takeaways from this place is transparency, honesty and quality. As a car enthusiast, I found a particular vehicle here I was interested in, and I worked with Peyman Reisi, the manager of Cars Unlimited of Santa Ana and I had a great experience. From Peyman to his employees everyone was extremely courteous and helpful. They were prompt to answer any questions I had about the car prior to coming in. They provided me with a Carfax and Autocheck report upon arriving and gave me ample time to check the car out and even allowed me to take it out for a lengthy test drive. The staff was fully transparent about anything they knew about the car and also fully encouraged me to have it checked out by a mechanic or dealership of my choice if I wanted to, of course, at my cost. If there were any issues, Peyman and his team said they would work on getting it sorted out, or reimburse the cost prior to finalizing the deal. You have to remember, this is a used car dealership, not everything is going to be perfect, it isn't a new car, but they will strive to make sure they get you into a solid, reliable car. Not even a large franchise dealer can guarantee something won't go wrong a few weeks down the road, that is why Peyman stands by his cars and offers a warranty if things do happen or allow you to get it fully inspected prior to purchasing. The entire team here was not pushy nor did they use any of your typical sales pitch when I was viewing the car. They were very hands off from the moment I pulled into the parking lot and the moment I left with the car. They gave you just the right amount of attention without being overbearing and pushy on the sale, whether you buy a car or not, they will treat you the same way they'd want to be treated. I observed this with different customers they interacted with. They have a very good selection of cars, and if they don't have what you're looking for, they can help source it for you and have it fully checked out prior to you purchasing it. At the end of the day, use your due diligence when buying a used car, whether it's from a smaller dealership like this one or a large franchise one. Not every car will be perfect, but it is the actions and integrity of the dealership that will set it apart. I am sure Peyman and his team will take care of any customer that have a reasonable issue with their car in a timely manner. Thanks again Peyman, I hope to see you around!

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.
