Used GMC cars for sale near Walnut, CA

My experience at the dealership was excellent from start to finish. Abraham greeted me right away, took the time to understand what I needed, and answered every question with patience and detail. The entire process was fast, smooth, and professional. I truly appreciate his outstanding service and the overall efficiency of the team.

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

Tustin Buick gmc went above and beyond my expectations. Super friendly and helpful staff. They were able to answer all my questions and concerns. I would definitely recomend buying a vehicle from this dealership. Thanks again Tustin Buick gmc for all of your help.

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.

My truck was service and clean in the time promised. The service advisor are allows courtesy and helpful. The dealership and waiting area is clean and easy to assets

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

Trey helped my husband and I get our first family car! The process was easy and the deal was great!

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 dealership!very helpful and workout a great deal!caleb was very helpful and found the best deal for us,come check them out and ask for Caleb

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.

Johnathan's a weasel. Ask for Caleb he'll take great care of you. I skipped work and drove 3hrs to the dealership for my appointment only to find the car had been sold and Jonathan was nowhere to be found. Caleb was kind enough to step in and make things right.

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.

Prompt responsive has good deals on used vehicles worth a try and buy with them

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.

The Audi Q3 S Line purchased from Audi Fletcher Jones Costa Mesa was my wife’s favorite color, blue. After an introductory text from Austin, I was coordinating an OTD price for the specific stock number. Mo Masadeh (Sales) contacted me and within an afternoon came to an OTD price and scheduled appointment the next day. Mo was amiable to deal with during the whole of our negotiating via text (my preferred contact) and via phone. The sales process was low pressure and professional. In fact, everyone that I dealt with, Collin (Sales Manager) and Peter (Finance) were absolutely professional. I found the vehicle my wife wanted and traveled from the Inland Empire to make my purchase at Audi Fletcher Jones Costa Mesa, so that says something about both my tenacity and the overall professional and amiable experience with this dealership. Thanks to all of you for providing one of the best experiences in car-buying that my family has had in over forty years of car-buying.

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?

I made an appointment for some recalls on my car, and a warranty related issue. Everyone was friendly and helpful. I was updated on everything dealing with my car, and it was even washed when I went to pick it up.

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!

Love your customer service thank you for your help and advice about my car service Lisa i really appreciate. I really recommend this place thanks.

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 service friendly and helpful had my Yukon worked on warranty service Ceasar Rivas was helpful and took the time to call me on every step.

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.

The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want

Mark Christopher GMC is an amazing Auto dealership. No sales pressure and terrible prices. Johnathon Villa was an outstanding salesman that helped us get a 2022 Canyon Elevation. He took extra steps to help us find the perfect truck for us. We drove over an hour. And so glad we did. Highly recommend. And I want to say thanks again to Johnathon for making the experience great.

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 fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

Marco delivered excellent service!! Overall great customer service and very knowledgeable. Will continue scheduling with him.

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.

Jakelin helped me to find a great car. It perfectly fits my request and had a good price. It was a pleasure to buy a car in this dealership.

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.

Love this place , love the service, love how fast my process was to get into my M4 .best dealer I’ve ever made business, super polite , humble and very respectful, they even car washed the vehicle, man come one I was like whatttt!!! Super happy I drove out from Hollywood and I was not disappointed. Check it out for yourself!!!!!!

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 !

Enjoyed my experience here at this dealership. Came out with a brand new car! Anthony was extremely helpful and guided us to find the car we were looking for.

They been really good to me !love my car runs great .pablo was very nice an friendly

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.
