AMAZING DEALERSHIP AND PEOPLE
Honestly the BEST car buying experience we have ever had:) I highly recommend Gay Family Auto Trey, Kiss and Steve are amazing. From the time we walked in to the day that Trey delivered my sons truck it was ABSOLUTELY PROFESSIONAL.
This truck has a jerk when changing gears sometimes.

Good service and help at Ron Carter.
Misa was very professional and helped me to get the auto I wanted. He was very helpful 👍 my Gladiator came in as ordered. Misa kept me “in the know” regarding status of my incoming vehicle. I would recommend others to use him as their sales person. I have already recommended Misa as a sales contact. The overall dealer appears to be well ran.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

I had an amazing experience working with Trevor when purchasing my Ford Explorer Platinum! From start to finish, he made the entire process smooth, stress-free, and enjoyable. Trevor was incredibly knowledgeable, patient, and honest ? he took the time to answer all my questions and made sure I was completely comfortable with my decision. He went above and beyond to find exactly what I wanted and made sure I got the best deal possible. I couldn?t be happier with my new SUV and the top-notch service I received. If you?re looking to buy a vehicle, I highly recommend asking for Trevor ? he truly delivers five-star service!

I'm very pleased with this dealership.
I'm very pleased with this dealership. Top-notch service, friendly staff, quality vehicles, and a great level of personalized service. Rudy was the best salesman I've worked with, and this is the 7th car I've bought in my many years driving. I'm really impressed with the automobile I bought and with the price. Truly a no-haggle and no-hassle deal. Hamida made the financing paperwork easy and quick. I've already recommended them to two coworkers and I will be shopping for my next vehicle here too. Thank you again Rudy!

In regardsto fixing a blown fuse on my 2024 sierra 2500.
In regardsto fixing a blown fuse on my 2024 sierra 2500. Diagnosis for $250 was applied to the bill for fixing the item which was basically a wash as the labort to remove a few exposed nuts on top of the battery cost about the same. But the repair allows me to keep my factory warranty, and for $600 after a generous $50 discount, I will sleep well knowing GM had my back.
