Used GMC cars for sale near Walnut, CA

love my new kia sportage thanks frank the tank. ask for frank if your looking for a smooth transaction

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Best experience I’ve had at a dealership by far. Fabian and Francisco were super helpful and went above and beyond to figure out something that worked for me. Highly recommend!

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Hector jacinto of Champion Chrysler in Downey is the Best sales men He explain all the details of our car Trading my car in and put a down payment down and got my notes where I want them

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Had a fantastic customer service experience with Miguel at California Motor Trade 3. He was incredibly helpful and knowledgeable, making the car buying process smooth and stress- free. He explained clearly everything, no pressure at all. Highly recommend them!

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

Friendly people and good service?.Will definitely recommend to my family and friends?,Got my Silverado with all the features that I was looking for..

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.

Austin, Zach, and Jaime were exceptional , they got a a great deal would definitely recommend to family and friends!

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.

Caesar was great from the moment we came to this location . He did the impossible and was able to get me approved for my dream car !! Highly recommend

We are very happy with our Terrain Denali. Our first choice was the 2023 Lincoln Corsair 1a but there are no in inventory. The Terrain Denali was 1b. Great styling exterior and interior

Nice staff, great selection of Tesla vehicles. Good prices. It took a while to get seen but they were short staffed. Unfortunately I wasn't able to get the car. But I will be back for it soon.

Tons of room , plenty power , very fancy and high tech for a truck worth every dollar and look very nice on the outside

Caesar Quintero Always make it happen for us!! He provided great service and insight in purchasing our vehicle.

Fast service. Went in for a recall after purchase 3 months ago. Was out in under an hour

So far the car is going great. We have had no problems driving everywhere and so far had no need for services. It is a great care for me and my husband,

Their inventory is Connected to numerous dealerships, made finding the right car easy and smooth, GM Mike, really helped me out and I left with a car 3 years newer and with half the miles than the vehicle I was originally financed for with my bad credit

Outstanding Family SUV - 8 Years of Reliable Service I’ve owned my 2016 Yukon Denali XL since it rolled off the lot, and it’s been an exceptional vehicle for our family. The ride quality is remarkably smooth, even on longer road trips, which makes every journey comfortable for all passengers. As a family SUV, this vehicle truly excels. The spacious interior easily accommodates our entire family with room to spare, and the third-row seating is actually usable for adults, not just kids. The V8 engine delivers plenty of power when you need it while remaining surprisingly efficient for a vehicle of this size - the cylinder deactivation technology (V4 mode) really does make a difference at the pump during highway cruising. The technology package has been a real highlight. The heads-up display keeps important information right in my line of sight, which enhances both convenience and safety. The rear entertainment system with headsets has been a lifesaver on family road trips, keeping the kids happily occupied for hours. My only complaint over eight years of ownership has been some paint fading on the hood, which seems to be a minor cosmetic issue that doesn’t affect the vehicle’s performance or my overall satisfaction. If you’re looking for a full-size SUV that combines luxury, space, capability, and comfort, the Yukon Denali XL is hard to beat. Highly recommended for families!

Maria Sanchez, Christian Campos and Sales Manager Rene were nothing but exceptional in the process of purchasing my vehicle. With the exception of a couple of other factors that weren’t pleasing, but these 3 individuals made it all worth while and a great car buying experience. Thank you!

I highly appreciate the professionalism and efficiency at STG Auto Group. Maria made sure I was accommodated throughout the whole process. She was polite and always elaborated when I had questions. I’d highly recommend going to STG Auto Group for your next vehicle purchase. Ask for Maria, she made it easy.

Perfect . If you want to get good emotions then you need this GMC Yukon Denali XL . L M k if you have any questions please

It was such an amazing experience I totally recommend Luiz was super helpful and very nice!

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.

These guys were great to work with. Shout out to Andrew, Eddie and Harold for their hard work. We bought an 04 Honda Element from them a few weeks ago and I have no complaints. These guys work hard to make it as easy as possible to buy a car. They were easy to work with and no high pressure to buy. I gave them 4 stars only because I wish we could have haggled the price down a little bit, not because of customer service. Thanks again guys for all your hard work. Wayland Collins

great car has everything and then some. lots of seats and 2nd row heated is cool. it could use a little more under storage in the rear compartment and a cover

Even though my Gladiator was in the shop for nearly 8 weeks due to a parts shortage, I had a very positive experience in dealing with the service department. Michele is a top notch service advisor, who genuinely cares about her customers, and is quick to return calls. Thank you Michele, you have a return customer in me.

So far so good! Beautiful ride and very comfortable. Love the smooth ride. Will be perfect for traveling with our parents, children and grandchildren. Thanks!

I had an amazing experience yesterday at Tustin GMC & Buick with Seth R.. I called him the night before to ask about the Sierra EV 2025, and he got right on it! We got the deal done in minutes, charged up the truck, and it was waiting for me to pick it up the next morning because I couldn?t make it that evening. This dealership is incredible! I usually buy luxury vehicles, and the service was just as great as when I do business with Porsche or Land Rover. George in finance was nothing short of amazing as well. The management is doing an incredible job keeping them going because they have such a great team. Every turn was met with a smile, and even in workout clothing, I felt like a valued customer. Thanks to Seth and George, this dealership is now my new pick-up truck home, and I?ll definitely be buying my pick-up trucks through Tustin GMC & Buick in the future.

First time customer, well taken care of. I will be back. Went to another dealership for service and was told my car would sit for 10 days before being looked at. J Star had my vehicle back to me in 3 days.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Dominique is very good customer service in my buying today for the Ram 2500 working with him was very easy

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!
