Used GMC Sierra 1500 trucks for sale near San Dimas, CA

Service was completed much quicker than expected. My concerns were noted and one was addressed. The other they did try to recreate but we’re unable to at this visit.

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.

David Gutierrez gave me a great experience buying my first new car! He was very patient and informative. I test drove 2 different cars. David also followed all CO-VID procedures which I was very happy about. I’m happy with my experience here. Thank you!

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Outstanding process with Metro Nissan in Montclair. Raj our sales person was fabulous, he genuinely cared and helped us through the process and in finding a vehicle that met our needs. We didn?t feel the pressure and enjoyed the experience.

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

Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

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.

Service writer was very engaging and informative. You can tell he enjoys helping customers with his positive and upbeat persona. Work was a completed as instructed and on time.

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!

Ashley is top notch with knowledge and service and patience! Everyone at the dealership is helpful and accommodating. Thanks for everything, Ashley!

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.

No comment last purchase and service at MK Smith. No rely, no reply No comment No comment, Hate I can?t get out of this unless I make comments

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

I bought a 2004 Pilot a month ago here. My salesman, Tim, knew exactly which loan to submit me for because I had no job and bad credit but a big down payment. He had me financed with no problem in minutes. A few days before I went to Carmax Burbank for a different car but with the same down payment and the saleswoman there did not do the same thing. The car was purchased in 2 hours and I was driving home. I bought the warranty tey offer which is a great bumper to bumper extended through their company. They have a 5 day return policy. I opted to return my car on day 4 to pay for the warranty in cash so as not to finance it at the very high interest rate I bought the car at. The return was also easy and everything was done in less than an hour. A month later now, I have found a few things wrong with this 2004 that seemed to have slipped past their extensive reconditioning program. I took it in with odd complaints a dealer would normally say they couldn't duplicate. They addressed them all and even gave me a loaner SUV for my babies to fit in while I waited the few days for the parts to arrive. GREAT STORE! Great customer service! And there's a play room for the kids! *Avoid the coffee!! It is terrible!!!

The people who worked at the desk were very kind and polite. They took the time to explain everything that was done. But whoever worked on my car did not reset the alert that says my car needs service. So every time I start my Subaru it states i need immediate service. I have also been waiting on a sensor part for my Forrester since December 2022. I have not heard anything yet and have reminded them about the part twice already.

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.

Ordered a Dodge 3500. And am waiting for it to be transported. The ill trade my car for a truck.

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!

Josh and Justin sold me a great Maserati. Customer service was great overall definitely recommend

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.

Compré mi camioneta 2018 Chevrolet Silverado con Sterling Imports me trataron muy bien los muchachos del dealer. Estoy muy contento con mi camioneta muy limpia y bien cuidada, me trataron muy bien se los recomiendo a toda mi gente. No se ban a repentir.

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.

Jay, was very professional and courteous he got me in and out really fast!! I would definitely recommend J Star Chrysler Dodge Jeep Ram. Thank you

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Although the car we wanted didnt work out, the customer service was excellent. MARCUS is a STAR! He should be in management. I have brought many mercedes in the past. Carmax is turning the tide when it comes to purchasing vehicles. The best thing to do when you buy any car is to take it to another mechanic, and then bring it back to the place to be fixed within the warranty period. The Truck I purchased from them a year ago had a few issues but they did take care of it and I've not have any problems since. Carmax has set the bar high for purchasing returning and anything to do with cars. BRAVO!

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I want to commen on our salesmen, Chase Morris. He was so helpful and work very hard to make the situation easy for us. Janet Lanoil.

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

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.

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.

Great experience. Simple and easy. Great staff. Definitely would recommend.

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

Hi my name is Abdullah Mojedidi and I live in Menifee CA and I just recently bought my beautiful used 09' Mercedes Benz ml350. I loved the color combination from the exterior to the clean interior. All in all felt great on the test drive. Great costumer service and communication by Robert he always got back to me in a timely manner. I happened to show up on a Sunday when my bank was closed and I had no ride to get back to where I needed to go and the gentlemen at Pro X motors even got me some lunch and a room nearby that was very convenient and much appreciated. I'd definitely recommend all my family and friends to Pro X Motors for their next great car!

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!!

I was running late past there closing time. They were very gracious and waited for us. Very nice to do business with.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.
