Our Reviews
Our sales person was either inexperienced or untrained fully. He had very little knowledge of a used car that’s been on the lot for a while. My daughter and I had sat down in the negotiation process and explaining that my daughter was going to be the primary owner of the car. I asked for an out the door price given she has a budget she can afford. Without asking or saying anything, our sales person began asking my daughter questions. I stopped him and questioned why he was asking her questions for a credit application when we don’t have a price. I will say the sales manager was able to make the price very reasonable for my daughter.
Jordan and the manager on site were very nice and helpful. Unfortunately, the vehicle that we specifically visited for was not cleaned nor the vehicle for us. Nonetheless, the experience was pleasurable.
I have always had a good experience dealing with Bill Kay. I have purchased many vehicles from them and all very easy.
Great experience I got the car I really wanted they went above and beyond to get me want I truly truly wanted same day no miles new 2025 Buick envista go get yall one
Everything was done in a timely manner and they treated me like I was the only client they had.
I trust this "Bill Kay" to find the car with all the feature and color I am looking for, they went Extra mile to match the color we were interested across the states and found the car. "Sallaudin Zamindar" was great in communicating and getting the best deal for the trade in offer. I had lot of back and forth about the feature and options for the Hummer, still has was able to work with us to get the best deal for us. This is second car we bought from Bill Kay. They are way better compare to other GMC dealers. I recommend this dealers to find the best deal for you !!!!
Was an amazing experience for me and my family at moment to buy our sierra Denali
Bill Kays was a great experience! Sal worked with us finding the best option to fit our budget. Not only was he so kind, but he is a new friend! As two women car shopping we were concerned about our safety/experience and it melted away quickly with Sal. He was knowledgeable about the cars available and was careful to not show us anything outside of the budget. We also worked with Sassan in finance- he was wonderful with showing us the available extended warranty options and providing peace of mind. It was a painless process and we left with our vehicle same day. More car dealerships need salesmen like Sal who bring humanity into the car shopping experience. Sal has a customer for life!
Sal is an absolute asset to your company! He made the car buying experience sooo painless!! Car shopping as a woman can be extremely intimidating but he was so down to earth and honest. I couldn’t have even imagined how amazing this experience has been. Thank you so very much and you are very very lucky to have an employee as phenomenal as Sal.
Service department staff was incredibly helpful and knowledgeable. My car was fixed with no issues and I had a great experience and will be returning.
Great staff all around. Wouldn’t recommend going anywhere else!
They not only had the best price of all the dealerships I checked, but they worked very, very hard to get all the rebates and incentives to which I was entitled, they were supremely kind and respectful about my wishes for what I wanted and didn't want, and the final cost matched exactly what I had expected - no surprises or junk fees. Jordi was eminently pleasant to work alongside and the whole team deserves accolades. I don't buy many new cars, but when I do, I always have that buyer's remorse of wondering if advantage was taken of me - but not this time! I left feeling great and still do.
Sal is a great worker, he got me set with an awesome car that absolutely love and enjoy. I would for sure go back to him when I decide to get another car.
Treated me well, did feel like I was taken advantage of or screwed over. That is rare now a days
Service was faster than average for a dealership, and first visit was on the house. Doesn't get better.
Jasmine has only one goal, to end any interaction with a customer as fast as possible, regardless of outcome or effectiveness.
As I am aware whenever the car is in for service and when completed it's supposed to go thru car wash. That was not the case and I had to request for it when I came to pick up my car.
Jordyn was a Great help in my car purchase journey, I recommend him to anyone who’s looking to purchase a new or used vehicle!
Car was leaking fluid, called Service and Justin was able to get in quickly & Service it.
I had major work done on my car and I couldn’t be happier with the turnout. I had my transmission replaced along with a couple other issues on my 2017 vehicle. It took a while for the entire thing to get completed, but I was given status updates throughout the process. I picked up my vehicle late last night (5:45 pm). I was surprised the service manager was still there and he took the time to go over everything that had been done to my vehicle. The total price was slightly lower than what I was I was told it would be at the start. I was very happy and wasn’t expecting that. My car is driving great today and so far I’m extremely happy with the result from my service experience. I’m very appreciative of the help I was given and the customer service I received. Thank you Justin and everyone who worked on my car. 😊
Was taken to work , the fixed the car promptly and called me to pick me up. That services itself is invaluable. Car runs well. Service department were knowledgeable and did a great job. That has not always been the case.
I recently had the pleasure of visiting Bill Kay Buick GMC for some service work on my vehicle, and I couldn't be more impressed! Justin in the Service Department was incredibly helpful—he made sure the work was completed promptly and at a very reasonable price. The dealership is conveniently located right off the highway, making it super easy to access. Whether you’re buying a car, getting service, or needing body repairs, this place truly offers it all. I’ve definitely found my go-to dealership for everything I need. Highly recommend
Juana Was WONDERFUL. We have just started our car search and we have been to a few dealerships and we are extremely pleased with her service. Thank you for a pleasant Experience. Debra
Always an excellent experience with sales and service staff!!
