If you want excellent seamless customer service, go to

If you want excellent seamless customer service, go to Tony Shine and his staff. He doesn’t have awards for nothing! He proves this in his work and professionalism each and every time! I have experienced his amazing customer service Now with my second purchase, and he went above and beyond for me! I really appreciated it so much! I will always go to Tony, for any future car purchase. I also want to give a big shout out to his assistant “Andrea Jewell” she was so great and helpful and communicated well. Another big shout out to “Matt Juron” Finance Manager who was also very helpful and understanding and made things happen! They are the best of the best! Thank you all for a great experience! I appreciate all of you!

Everyone at the dealership was friendly and professional.

Everyone at the dealership was friendly and professional. Reva handled my purchase for my first luxury brand vehicle and is absolutely amazing. She made it all come together smoothly and was a joy to work with. It’s the third vehicle someone in my family has bought from her and we will keep coming back!
