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

The experience was great. Worked the numbers over the phone and nothing changed when I arrived onsite. They value creating long term customers.

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!

We had an amazing first time buying experience for my son. He learned a lot and was pleasantly surprised how being a costco member could help us at Autonation Both our salesperson and finance manager were friendly and helpful.

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.

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

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.

I purchased a truck for my business here after having a bad experience at another dealer. Aaron personally went to their second location to pick my truck up. Thanks Pacific

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. ??????????????????????????????????????????? ?????????????

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

The service team always makes sure we are well taken care of. Shout out to Fernando Trejo and Luis Mejia for continuously providing an ?over the top? customer service experience whenever I bring my vehicle in for scheduled maintenance.

I worked with Mike Velasco and tj boldt. They were great at explaining the whole picture and not leaving any questions. I feel I got an honest deal with a great customer service.

Very good buying experience. It was quick, and easiest time I've ever had buying a car. Never felt they were pushing it on me, or trying to upsell me.

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!

Was assisted by Esteban and the Manager Albert in the purchase of a used vehicle. They were upfront and helpful. After purchase, took the vehicle for an inspection. The vehicle checked out as they had stated.

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.

2 years later and I’ve come back to do business with Anaheim Hyundai. Let me just say I had a smooth and professional process. Jerron was a delight to work with he was very professional and communicated with me through all the process he was able to go step by step on warranties and helping me choose the right car. I traded in a vehicle and left with a Tucson SUV I am very happy with Hyundai in Anaheim thank you Jerron for the great experience. 2 years ago I had a bad experience but you definitely have turned that around and hope to come back in the future and get myself a even newer car !
