Service
Service was on time and complete. Service personnel were polite and professional.
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.

Great Buying Experience!
Great experience today at Buick GMC of Vacaville!! Mike Vasquez was our sales guy, and he was very friendly and helpful. He had the truck we were interested in all ready when we stopped by to take a look. Mike is very knowledgeable and treated us extremely well. It was an efficient and stress-free buying experience. The finance department was also great. They were very upfront and quick. Thanks to Buick GMC of Vacaville, I have my dream truck!

Izzy and Sheridan were extremely helpful.
Izzy and Sheridan were extremely helpful. I really like the fact that I felt no pressure at any point to buy a truck. I will definitely buy from them if we can get the right vehicle.

I visited the dealership because my tailgate would not
I visited the dealership because my tailgate would not close. They were able to give me a quote. Get the part and make the repairs within hours. The service staff was courteous and attentive, offering me shuttle service home and back repairs are being made.

Everything was negotiated by phone and email.
Everything was negotiated by phone and email. I was done and not expecting to buy because the cost was slightly more than I was willing to spend. The dealership is approximately 170 miles away. Finally, and after I had given up, David Messanio made an offer I was willing to accept but he wanted me to make the purchase within 2 days. I agreed to drive to physically look and if satisfied, purchase the truck. Once at Vacaville GMC, I was warmly greeted and treated friendly yet professionally by the entire staff there. The purchase went off without a hitch. I would recommend Vacaville GMC and the team there to anyone.
