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. 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 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.

When you go ask for Enrique as your sales rep. One of the best experiences I have had at a dealership. hate doing the whole back and forth, let me show you our rates, let’s not negotiate on price but on payment. I came in pre approved with my credit union. Wanted to look at 3 suvs. I went on two test drives. Went through the whole car to see the items that were scuffed or messed up slightly. Then made my decision of which one I wanted. Told them the number I thought was fair. And in less than 2.5 hours made my decision. Enrique thank you again for being kind, easy to work with, educated on what I needed. It was great.

Great experience buying from out of town, got picked up from the airport and was out quickly. Great service.

Arian was my salesperson. He was the way you would want a sales person to be informed, but not pushy. I would definitely buy from him again.

I had an excellent experience working with Nabil at Elk Grove Buick GMC ,from the moment I walked in ,they were very friendly , knowledgable and truly listened to what I was looking for in a vehicle ,he tool the time to answer all of my questions explain the feature f different models, and never made me feel pressured the entire process was snotty and stress free and I drove off feeling confident in my purchase if your looking for a great car buying experiences I highly recommended Nabil Ashofta .

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.
