Used GMC trucks for sale near Upland, CA

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.

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?

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

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.

Quick friendly service. Jay was Awesome! My truck was fixed fast and didn't coat much. Appreciate all of you guys. ??love yall yall the best

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 !

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!

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.

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

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!

Chase in the sales department recently helped me with my new family vehicle. I have always used him as my contact for sales related items. He is extremely knowledgeable with current market trends and is fair and honest. I would highly recommend him to my family and friends. Thank you again sir.

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.

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

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.

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.

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

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.

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!

Xavier, Sebastian, Aaron, and Nicole were all helpful and good to work with! Thank you!

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.

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.

Michael Jacobs made the car buying process seamless when I purchased my 2025 Yukon AT4 diesel. He was extremely helpful and polite😊 Rod Shelffo in Finance was awesome to work with as well!

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

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 bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

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.

I have bought 2 work trucks from this place and they were both good and reliable. The sales people were pretty good except for the second time around, he actually got frustrated when my wife started reading the contract before signing. The only issue I have is both times I purchased, the trucks gas tanks were on empty and they wouldn't put any gas in them for me. The second truck I bought, the tank was so empty that I was stressed leaving the place just hoping to make it to the gas station across the street.

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.

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!

It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

After getting the run around from multiple dealerships in LA/OC/IE I visited Auto Republic. Yes, I had my guard up after all the financing and heavy down payments other dealerships we're asking for before even giving me attention. The showroom was clean and the lot had so many dream cars. I found the perfect car for my family and had the assistance from the manager that was top notch. I'm writing this review since the single star reviews show the lack of reading details about add on features. Don't get upset with a dealership for having tracking on a car (saves on insurance) along with other key options that are great for your next car. I've referred family and friends, all had exceptional purchasing experiences and I'll get my next vehicle here as well.

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!

This was one of the best experiences I had purchasing a vehicle everyone was kind a very knowledgeable. This was the quickest I've ever purchased a car thank u !!!
