Professional and courteous!
Fantastic dealership with professional and courteous staff.
So far so good!
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.

Victoria Gia and her sales manager did an excellent job
Victoria Gia and her sales manager did an excellent job of helping us without being too pushy. They stayed late after the dealership was closed to help us.

We had an outstanding experience purchasing our new car
We had an outstanding experience purchasing our new car from Santa Monica Buick GMC. From start to finish, the entire process was smooth and professional. The team was incredibly knowledgeable and made us feel confident in our decision. We want to give a special shout-out to Victoria, who went above and beyond to make sure everything was perfect. Her expertise and attention to detail were truly impressive. She answered all our questions with patience and clarity, ensuring we fully understood every aspect of the vehicle and the purchase process. What?s even more impressive is that Victoria continues to provide exceptional support even a week after the purchase. A week later, she?s still available and responsive, patiently addressing any questions we have with the same level of professionalism and care. The warm and welcoming atmosphere at Santa Monica Buick GMC made all the difference. It?s clear that customer satisfaction is a top priority here. We?re thrilled with our new car and highly recommend Santa Monica Buick GMC to anyone looking for a top-notch buying experience. Thank you again to Victoria and the entire team for making this such a positive experience!

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

The prices attracted me.
The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want
