Used 2023 GMC Sierra 1500 trucks for sale near Montclair, CA

True to word, respectful to customers and their time. very happy with the purchase, without trying to sell me other stuffs. thank you for pleasant and easy transaction.

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 Great working with Ronald. Very easy to work with. We love our Tahoe!

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.

A lot of the negative reviews on this place are a bit silly. In my experience from this past weekend, if you listen to the salesperson who you are assigned, bring all the documents requested, make appointments, and come fully prepared, you will have an excellent experience just as I did. I placed a 7-day hold on the exact car I wanted, and made an appointment to come test drive it and apply for financing a few days later. I spoke with my salesperson, Jerry Neyland, a few times on the phone before coming in, and he always had the answers I needed. He advised me on what documentation to bring with me, and when I arrived for my test drive appointment Jerry has the car ready for me. We took a quick test drive, I fell in love with the car, and we started the financing application. Since I brought everything we'd need, it was a BREEZE! In total, I was maybe at CarMax for 2 hours maximum. I had been stressing over it all week, only to find out it was all so, so simple. Jerry's customer service is second to none--he was friendly, quick, and understanding. He kept me informed every step of the way, and not once did I feel he was putting pressure on me or trying to "sell" me on anything. CarMax Buena Park gets 5 out of 5 stars for me, and Jerry Neyland gets 6 out of 5 stars! Overall an excellent experience in every regard.

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.

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!

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

I?ve been having my vehicles maintained at Selman for years and have never been dissatisfied. They do great work and keep you informed on your vehicle?s condition. The service representatives do a great job.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

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.
