Used GMC cars for sale near Walnut, CA

Call to about a concern with my check engine light. Was done fast an efficiently was a power train issue and was fixed correctly. Truck is running fine.

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!

It was a pleasure to do business with them. Accommodates me well, everyone is very professional and helpful.

I had a terrific experience dealing with Kenston now for the third time buying a vehicle. I highly recommend this dealership as they make the entire process very easy and low pressure. Matt was a terrific help to me answering questions and easing the buying process. I ended up purchasing a terrific truck, low miles and every bit as new as driving off the Ford dealership lot. Buy from Kenston, you won’t regret it.

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 am satisfied with my visit. I do think more thorough inspections should be done. My headlight was out and I knew this before the visit, but on the checklist it was marked as good. I love the cookies that are left after service visits as well .

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.

I purchased a 2025 Mazda cx70 with the help of Kenneth at Boucher. He wasn’t pushy and actually made the whole car buying process a little less terrible! The manager was also willing to work with me on numbers to suit my budget. If you’re in need of a Mazda, ask for Kenneth!

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.

Harris was the consummate professional. From start to finish the professional Acura Ambassador all the way. The most through vehicle accessories explanation to his gentlemanly demeanor. He was easy to work with and explained everything completely. We throughly enjoyed the car buying experience. Thank You Harris! Sincerely, James & Katherine Little 2023 RDX ASPEC

They were great to work with, I tested an Explorer and it was very nice, but on a front wheel drive platform, and I needed an Expedition and they didn't have 1 at the time.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

Desmend is the best he made the process super easy made it a stress free purches he is really nice not a pushy salesman at all i will send everyone in my family and my co-workers as well the dealership has this Amazing lifetime warranty for the engine transmission and drive Axle lifetime powertrain warranty and their inventory is trully amazing Desmend is now a personal friend to me and the only sales person I’ll ever Work with he has changed how i view salesman

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

"Me and my family purchased four vehicles from Auto City...." - brianwoodward57 Me and my family purchased four vehicles from Auto City. Each time, there is no nonsense, no pressure and no games. They are very helpful when choosing a car and getting financing. There is no price haggling because the prices are extremely fair...and I know how to verify the value of a vehicle. I recently purchased a 2019 Nissan Sentra with all the fixins'. I purchased the car for about $900 less than any other dealership I shopped. Plus, it was in great condition, except for some minor things one would expect a used car to have...but their service department fixed them very quickly and perfectly. My last car I purchased at Auto City was a 2011 Chrysler 200 which had 54000 miles. I am still driving that car in the family and it currently has 218,000 miles. My son bought a Toyota Matrix and drove Uber for 3 years, trading it in with 230,000 miles. Another car bought was a Chevrolet Malibu that was purchased and is driving great with no problems and well over 100,000 miles. All of the cars we purchased had no problem other than an alternator, battery and minor things like that when cars reached over 160,000 miles, and this is to be expected. We never had any major issues with any car, and no problem until many miles later after purchase. My most recent purchase at Auto City took in to consideration that I was self-employed this time. Isaac Duran, the finance manager, did everything in his power to get financing with a lower interest rate, and he did it. All I can say is that if you go anywhere else, you will pay more, put up with weird sales games and miss out on an easy, positive experience in buying a car. And, to boot, they will stand by your car for 6 months, 6,000 miles along side the dealer warranty (they have a huge auto service department to ensure the cars they sell are good). They have always backed us up and made buying a car a positive, easy, confident and a no-risk transaction. Anywhere else I went to check, I always got the "weird-ar" pegging out. Very good, honest people and great cars, with no worries! This is a very positive review, but there is truly nothing I can complain about after buying all of our family cars there for years. Talk to salesperson Mike or Alex...they are both very helpful, friendly and know what they are doing. The sales manager is great and ensures everything goes quick, smooth and I get a good deal.

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 !

I found purchasing a vehicle at Jerry Ulm Dodge to be a very pleasant experience. It's a very nice, modern facility with excellent amenities and a great staff. I highly recommend this dealership.

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

I've bought 4 vehicles from this dealership as a return customer die the the (CPR) - Courtesy - Respect - Professionalism I live in Delaware and make the journey for these three requirements for me to purchase. Ask for Lou 😉

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

Service was excellent, very helpful salesperson (Matt Bouchard) and finance person. I was surprised how much the salesperson helped, contacting insurance and even connecting my cell phone to car system:screen for me.

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!

It was a good experience, Nik when above and beyond to get the job done, was an amazing experience

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 Yukon has all the bells and whistles. It is a joy to drive, the drivers area is like a cockpit with everything at your fingertips.

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Amazing customer service! My salesmen Joshua Aguirre was incredibly helpful and really felt like he cared about my needs when it came to looking for a car!

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

I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Greeted well and by name. Service department found my unused voucher for service and I payed zero to be treated very well. Happy and friendly and knowledgeable folks spent their time helping ME. Mechanic?s video extremely helpful.

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!!

Always exceed expectations Holm is alway working to give best service and go above and beyond what is needed . Jamie the service tech is excellent and catches the little things If you want to buy a car where you know the follow up will be there. Holm is the place

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.

I bought my car here and had great experience. I appreciate their kindness They changed oil and it was great checked car out too for free. When done they explained everything.

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
