Our Reviews
Great Sales team and amazing service! Just bought my car from them. They gave me an amazing deal and great customer service!
Great service friendly atmosphere very informative. Easy going and a great place. I would definitely recommend to anyone in need of a new car.
These guys are the best in the business. Made everything super easy and stress free. Mena was very knowledgeable and got me everything I wanted. The manager Dan was also very nice and easy to work with. Will tell all my friends about these two.
Danny and Mena were both a pleasure to deal with. I had a very easy experience at their dealership, and would recommend to others.
Great dealership! Friendly and professional staff! 10/10 100% would recommend. Mena and Danny are THE BEST!!
Danny and Mena put me in the car of my dreams, great guys to do business with! Would highly recommend the both of them!
Daniel and Mena were amazing I came in looking for a new car and they were able to get me into a beautiful Fiat 500. Daniel told me how he had one and it drove so nice talked me right into it. Thank you guys so much for your help!

Amazing work! Great service he made the process very easy he made dreams happen. Very satisfied. Overall great person and great sells man highly recommend this place and person to speak to and get a vehicle from!
jordyn was very helpful and helping me find the car that I wanted. I came into the dealership not knowing what vehicle I wanted and Jordyn went above and beyond to help me get something that fitted my needs. I really appreciate everything that he did for me and I recommend him to everyone that goes to BILL KAY!
I’m a senior buying my first car alone and these gentlemen were so kind and patient. I was nervous but they made the experience fun. I ended up with a vehicle that I love. I will definitely recommend this dealership.
They were so pleasant, kind and helpful and met all my needs!!! Jordyn and Sisson are a great asset to the dealership and the company as a whole. I’ve never been to a deal shop that took care of me like they did. Also I was only there for a short period of time, which was great!!!! I’m so happy with new Infiniti truck!!!!
Jordyn was phenomenal. He went above and beyond to seal the deal. Also he ensured i was satisfied with my vehicle. Although they didn’t have the color i wanted he made sure i got a color i liked.
Juana and Joe were very helping us with the lease of our 2025 Buick Evinir. Very pleasant experience.
I just bought a brand new GMC Canyon, and I had a fantastic and seamless experience with Juana and Joe. I arrived at the dealership with a pre-approval from my bank, but to my surprise, they offered me a better rate with another bank. Additionally, I initially thought I would have to return to the dealership to pick up my truck, but Juana delivered it to my house today!
