Used 2021 GMC Sierra 1500 trucks for sale near Rowland Heights, CA

We had our oil changed on my 2018 suburban. Our service writer was Faith. She was very informative. She checked us in and reminded us of our Chevrolet rewards point. This is the first time anyone has asked us if we wanted to us our rewards. We have been having our work done at George Chevrolet since we purchased our suburban. I really appreciated Faith,s effiecency and keeping us informed during our visit. We will make sure we ask for her on our next visit.

I found the car I wanted at this location and they were super helpful in getting it transferred FREE to a location closer to me so I can go in to pick up.

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.

Good job, Great service, thank you. I will alway bring my car here

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.

Just want to give a shout out to Christian for a job well done! Great experience at the largest usud car dealership in the Valley! We were treated Very Well, couldn't ask for More! Thanks for all of you who helped us at CarMax!

This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

After getting the run around from multiple dealerships in LA/OC/IE I visited Auto Republic. Yes, I had my guard up after all the financing and heavy down payments other dealerships we're asking for before even giving me attention. The showroom was clean and the lot had so many dream cars. I found the perfect car for my family and had the assistance from the manager that was top notch. I'm writing this review since the single star reviews show the lack of reading details about add on features. Don't get upset with a dealership for having tracking on a car (saves on insurance) along with other key options that are great for your next car. I've referred family and friends, all had exceptional purchasing experiences and I'll get my next vehicle here as well.

This was one of the best experiences I had purchasing a vehicle everyone was kind a very knowledgeable. This was the quickest I've ever purchased a car thank u !!!

The experience here at Car Castle was by far the Best car buying experience my wife and i have ever had. Thank you Eddie the (Manager) for helping and assisting us with the whole buying process and for giving us a Great Deal!

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

The service staff were friendly and efficient. My car was serviced (oil changed and tires rotated) and ready in a timely manner. The waiting area and rest room were clean

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!

J Star Dodge has the best customer service of any place of business I frequent. They have been the only place I use to service my 2019 Dodge Durango. I have 69,200 miles and it runs like it’s brand new.

Very nice staff, I felt guided the entire time! Sammy and Rolando helped me out very much, making sure I knew what I was getting myself into and giving me the best options. They helped me buy a car and that feels great!

i just want to say that Jorge was so patient with me during the whole process and smiling all the time and even offered me lunch which is very rare these days he's really really nice and very good at his job. I dont have enough word to thank Jorge seriously And Mina the manager was professional as well very nice we had chat after i closed the deal very nice man gave me a lot of advices about cars that no one did before If you guys go u won’t regret it at all They will make sure to give u the best value in the market for ur car if u trade in or sell an give u good deal on their cars Dont look around if u want to buy a cat Best team best manager hands down ill buy my next car with you guys for sure ASK FOR MINA AND JORGE ✌️✌️👍👍

Pretty great experience overall. My sales representatives Maria and Rene were very helpful, answered all my questions and made the whole transaction quick. Highly recommend STG Auto!

Ronit was really patient with us , couldnt come to an agreement at first but was able to work with us all the way through till we figured something out . Again ronit was very patient and very kind. Will happily buy from them again in the future

My truck was service and clean in the time promised. The service advisor are allows courtesy and helpful. The dealership and waiting area is clean and easy to assets

Hello GMC Team, On February 28, 2026, I posted a review regarding my experience at Tustin GMC, specifically concerning the inclusion of add-ons during the purchase process. In my review, I shared that I felt pressured when I was informed that a protection package valued at $4,200 had to be included in order to move forward with the deal. Today, March 1, 2026, I received a call from Tustin GMC management apologizing for the miscommunication. They explained that it was not their intent to pressure me, and that the final price presented actually included an extended warranty rather than a mandatory protection package. I appreciate the clarification and the outreach from management. I accept their apology and want to acknowledge their effort to address the situation and make things right. This type of follow-up and accountability is what excellent customer service is all about. Thank you to the GMC team for taking the time to reach out. Your actions truly go a long way.

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

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