New and used 2025 GMC Sierra 2500 trucks for sale near Signal Hill, CA

Fantastic dealership with professional and courteous staff.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Professional and superb customer service. Was dealing with a check engine light. They go out the way to make sure customer is taken care off.

Had to get some warranty repairs done. Jeff took care of all the processing and we were informed about the progress from start to finish. Professional, courteous customer service.

Ok so I am sure my 1st review is not gonna be deleted but I have a new review for them as they have addressed my concerns and Because of 1 persons actions I am completely satisfied with the repairs and commitment that JOHN in service has made sure I was completely satisfied with the repairs so a big THANK YOU to John and anyone else who worked on this I will definitely be taking my truck back for service

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

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

Great service friendly and helpful had my Yukon worked on warranty service Ceasar Rivas was helpful and took the time to call me on every step.

I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.

William in the service dept is and always has been the model ALL of your service representatives should follow, especially the younger guys! William truly does care; he listens and goes the extra mile to help and fix whatever he possibly can- we've been dealing with Will since 2017 and wouldn't want it any other way- he's the best- HE is the reason why we stay at GMC. -Salvador and Priscilla Elias

Tom & Jerry in real life way better than the cartoon. Got me exactly what I wanted in a reasonable amount of time.
