Great work Ryan! Very thorough in providing exceptional customer service thanks for resuming wash activities after the abundance of rain this season

All in all a very pleasant experience. The sales person was so knowledgeable and the deal went very quickly I would definitely purchase from this dealership in future.

Very easy paperwork and pleasant staff the sales lady Michelle was very helpful with the process also Gary the salesperson is a nice and will help out when needed

Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

We've had only the best service with Diamond Hills. Everyone we have come in contact with over the last 2 years has been pleasant, courteous and helpful.

Mike over in the service department had great service for me very knowledgeable and took care of everything that we needed to.It was great service

I needed a 10k basic service on my vehicle. Everything went well, I will use Hatfield again.

Everyone was amazing at Mercedes Benz of Ontario. Great customer service. Diana was my point of contact and she was very helpful and insightful. Will definitely return here for my future services.

EXCELLENT!! Best car buying experience EVER. Jerry is educated on the vehicles, is kind, knowledgeable, considerate, listens. Seamless transaction and fantastic deal.

I didn't have an appt but they were awesome anyways. But nothing breaks on a schedule lol. I was helped quickly, offered coffee and a seat. They kept me updated on the car and how long it'd take for the parts. Thx guys, great job as usual.

I hade a Great experience at this dealership , Thank you Dylan for makeing my dreams come true. and to the finance depatment Freddy who made it very easy and fast, Icould not of had a better experience. I truly recommened Diamond Chevrolet Banning.

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

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.

First time buyer 12/12/2024 ..JP was able to help me with all my questions and needs to purchase my new sierra pro ..thank you JP you're awesome

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

We were happy with the service and time it took to complete our purchase. A sales rep (Jerry) worked with us over the phone and had many documents ready to go and prior to our arrival.

Dealer add ons are extremely high, we were able to work on some of those numbers. Still high after bargaining, but I agreed since I wanted this truck. When Mariah came back with financing option, I come to find out that we can't finance outside, it has to be their financing or pay cash! Can you believe this? After everything done with salesperson, had to wait for finance. Sat for over an hour &1/2. Employess kept walking in & out of finance office, some eating, while customer just waiting.
