Used GMC cars for sale near Walnut, CA

Not happy with the degree of energy some employees/ sales people were and most likely won’t come back or recommended Although Dom Was excellent With his communication and care He was one of the only one here with people skills

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

One of the best used car dealership in OC! I totally recommend it to all my friends and family. I am super happy with my new 2019 Mercedes Benz GLE!

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!

Keshan and Hamsa were Great through the whole process fast and quick will definitely buy again

Kris was great! Had a lot of patience with me and definitely will recommend him for your next car purchase.

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

The team at LSM Cars are amazing! The whole buying experience was great and the Finance team worked with me to find me the best possible deal that would fit within my budget. I will most definitely recommend them to family, friends and my coworkers!

Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.

muy buen servicio, kris me atendio consegui la gmc muy buen trato me hiso lo recomiendo

I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

We had an excellent experience all staff very helpful and friendly. It's was the best experience we've had at a dealership. They are so straight and transparent about everything we've asked. By far they exeded our expectations.

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,

Al’s one of the best salesmen I’ve came across..His customer service is outstanding!! He will get you in whatever vehicle you want..Thanks again Al for getting me in a 2022 dodge challenger BRAND NEW💯

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

Eduardo helped out fantastic please come get your son or daughter there first vehicle here!

Perfect for a couple. Plenty of room and should be good for trips. Room for another couple when going out for fun. Ride is very nice and has a lot of safety features.

I want to start off with the compassion this place has for the customers. I never once felt pressured for anything when being here and talking with the sales reps. I had the pleasure of doing business with Rami. He took things at my pace, was very understanding and I felt tried his hardest to get me into the car I so desperately wanted. He kept me updated on the car and walked me through each step making sure I was comfortable and answering my questions to reassure me of what was going on. Then came the gorgeous Vanessa who emailed me during the week to make sure my dream car was still available. When I went into the dealership she introduced herself and sat to talk to me even though I was working with Rami. She was very nice and also made my experience that much better. She honestly cared and I could tell by how passionately she spoke to me and could see it in her eyes. Last came Argenis who tried his hardest to get me the best deal I could handle. He was very professional and walked me through everything. He made the experience very comfortable and I am very pleased with my whole experience here. I would recommend 10/10. My best experience by far with any auto group.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

Excellent, Easy, No Gimmicks! Easiest Purchase I?ve ever made! Great people! Highly recommend to anyone looking to purchase a new vehicle! If they don?t have what you want, they will find it for you!

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

Good service would come back again . This is the second car we got from this location.carlos and Salvador are good people and would deal with them again.

Hassle free experience when I went into get an oil change with the help of Branden. Upon completion of service, I received an easy to read report outlining the results of inspection. Service department was very professional and helpful.

Adam did a nice job locating the vehicle I wanted to see. He went the extra mile tracking down the service manager, beginning the purchasing process, and ultimately ensuring the vehicle was ready for pick-up a week later. I found Adam to genuinely care that I had a good purchasing experience.

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

LSM Cars by far has been the best car buying experience I have ever had. They were very honest, sincere and made the whole buying process easy from start to finish. My sales rep Teo was very knowledgeable and patient while Erika the finance manager was looking to get me approved with one of their banks. I ended up trading in my 2010 Honda civic for a 2018 Mercedes-Benz GLE. I love my new car thanks again LSM Cars team. I will definitely be back for my next and will make sure my friends and family come to see you guys as well.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

Came in with no appointment, but was taken care of in a timely manner. Work performed while I waited in comfortable customer lounge. Had a cub of coffee.

Had my 2024 Canyon for exactly one year. Not a single real issue once over the air update was done and that only affected the radio. It was an AT4 in desert sand metallic. I traded it for a 2025 Acadia, as I missed life in an SUV. However if you want a truck, I’d highly recommend it and specifically the AT4 model. It’s got meaty tires for pothole protection, it’s able to tow more than you can imagine, it looks super amazing and you’ll have lots of thumbs up and positive comments when you get gas, etc. updated tech was more than you could ask for. 4WD auto mode worked flawlessly. Engine had a nice little growl that I miss too. Let me say if you are a truck person or want to be a truck person, it’s a perfect mid size truck. Mine was 100% and am missing it yes but love the Acadia because it’s also a great vehicle. Got the AT4 Acadia and for my situation it’s perfect.

Jonathan was outstanding. Got me what I needed and I was in and out within an hour and a half. That was incredible considering I came in at 3:30 last minute. Can?t say enough about his service. I?m giving a five star simply because of him. I will say that they did not set my tire pressure like they should, have.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Chris, My salesman was great! Unlike any I’ve had in the past. He really wanted make sure I got the best deal. The dealership staff was all very helpful.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

BRANDT was amazing ! My niece took ownership of the 2020 Fiat Spider He was EPIC! Highly recommend AARON AUTO !! The whole Staff is a pleasure. Mahalo, MJ

Great truck with a ton of room and a lot of compliments. Not gonna find a cleaner truck with only 44,500 miles on it. 20' inch rims with 35 tires on a 6' inch lift kit.

The experience was Great! Mr Lozano is a great salesman, he helped me with all my questions, all the process was very smooth and simple, all the team is great from Lozano, Tony and Yuri great people, I?ll comeback to do more business with them
