Jhonathan and his manager were seriously the best and
Jhonathan and his manager were seriously the best and friendliest salesman that I have ever had the pleasure of working with. When I buy a vehicle, I shop around for weeks/months. No one was willing to deal with what my main goal was and what I wanted and if they did, they were extremely rude and non personable. I would highly recommend Jhonathan for all your car buying needs.

Exceptional customer service.
Exceptional customer service. My Salesman Doyle and his Manager Zack listened to my needs and got me in a vehicle that was exactly what I was looking for. They were very helpful and not at all pushy. Made my car buying experience easy! Will definitely be back when it's time for another vehicle!

Had trouble getting my car after service. I was waiting on my car but they parked it in the lot. Had to wait 15 minutes for them to find it. Had my air filter replaced but they didn?t reset it.

The well coordinated team worked quickly to provide the
The well coordinated team worked quickly to provide the information necessary so that I could make an informed purchase decision. Representative Kensy was not only knowledgeable but very accommodating. In fact, I was very impressed that she was willing to go into the service area in the high heat in order to lower the vehicle that was on a lift whereby I could look at the interior. Further, her texts and phone calls kept me up-to-date on the progress of the necessary repairs. I noticed the cleanliness of the dealership as well as the positive attitudes of every person I spoke with. Overall, a very pleasant experience. James Simmons Overall, a very pleasant experience. Hey Siri, call Sonya Simmons hey Siri, James Simmons, James Simmons, James Simmons.
