Great customer service: competent, polite, efficient and honest. The body repair shop does an amazing job. They made a difficult situation as painless as possible.
Service department was professional and courteous and took care of my vehicle
Everyone that I met at the dealership was very kind and welcoming. They made me feel relaxed and answered all of my questions. I felt very comfortable with them and knew that I was in good hands when purchasing my vehicle. My 2025 Envista is a great vehicle and I look forward to many years of ownership.
Great service. Quick and easy to deal with. My car looks just like it used to.
We had a wonderful experience from start to finish at Bill Kay Buick especially the level of service Jake, the sales manager, provided.
My Service writer Jasmine was wonderful to work with. She kept me informed and updated on my services and the cost and timing of my repairs. She even sought out a discount to save me money when additional labor costs were incurred, as well as arranging for a free car wash even though it was under 35 degrees. All in all, everyone involved were great...except when I came to pick up my vehicle and no one could find my keys...which only took an extra 5 minutes. Thank you to the whole service department!
Quick complete service. Very friendly
Got me in early, diagnosed & fixed the problem under the quoted estimate… I could not be happier with the dealership & the entire Service Dept.!
Recently purchased my Tacoma from Jordi and I’m happy I went to them for it. From the beginning the sales manager Jake was straight forward and my expectations were met when I got there. No surprises from the sale and even when I was concerned about a potential problem after the sale, they stood by it and the service manager Justin took care of me. Sassan was also fair to me after I decided to get an extended coverage so overall I had a good experience.

Ken, in the body shop was extremely helpful and the end result of my car looks great
We have always received exemplary service from Bill Kay Staff, we have been customers for 15 years !
David and James Otten were professional and courteous. Will refer them both for service needs.
David was very helpful and informative I was treated with respect and informed of my vehicles progress every step of the way . After my car was was looked at for a piece of metal in my tire causing a flat David informed me that it was fixed and I didn’t need to buy a new tire that was awesome but that the other part of my service would take a little bit more time waiting for a part thank you David. Bill Kay Service department was great very comfortable atmosphere in the waiting area The night drop off service was great also so far I’ve been very happy with this dealership. Looking forward to long term business with them.
I was completely satisfied with the service . Thanks David .why is it a fifteen word minimum sometime less said !
Great service quick and easy they did a firt oil change and updated on the truck all good
Justin, David, and the entire service team are absolutely wonderful! I’ve been coming to Bill Kay Buick GMC for over two years, and while I’ve dealt with different service teams in the past, this one truly goes above and beyond. Not only are they extremely quick and efficient, but they are also incredibly kind and personable. I fully trust this team to keep my GMC running perfectly!
Very nice place. The salesman wasn't pushy, The finance department explained all our options and was wonderful in helping us. I can not forget the manager in all his kindness and efforts. May I say we bought a clean 2015 Hyundai at a decent price.
I brought my car in with some serious issues. Technician handled recalls, engine replacement, and warranty coverage perfectly. Jasmine and Justin took great care of me on the front end. Excellent experience throughout.
Holy Jesus, it took a minute but we got it done. Thank you guys, you are great and really appreciate all you did
Awesome work guys, many thank yous for being there for me and the struggle to get it done.
Needed key fobs replaced. They were ordered and came in within the next couple days. Scheduled the service appointment and all was completed within two days. Have received great service upon all my visits.
They did nice work when I took my vehicle in for body shop repairs. Would recommend.
Did what they needed to do to get the deal done and let us leave happy customers! Sal was a class act!
Sal is an amazing salesperson. His customer service is outstanding. He far exceeds expectations of a dealership experience.
