Dealership was professional. Took about an hour and a half to finally pick up the vehicle.
2020 Chevrolet Camaro I thought I had a tire leak but the tires are still good thank you for the great service

YOUR WORKERS TREAT ME WONDERFUL AND MY TRUCK LEAVED YOUR FACILITIES LIKE I SPECTED, THANKS
Avo was awesome. I came in with a warranty concern, and all though my initial perspective was not correct Avo was able to get me in direct contact with the service tech, Jong. They both listened to my experience and found a way to resolve my issue. It did take a little longer than I expected, but this duo was worth the wait!
We really appreciated the quality of service, and the ongoing updates from Tony at the Service desk. He was Terrific!
Got in and out quickly with exactly what I wanted. Fleet sales is great to work with.

Out of all my years, owning a vehicle in visiting a dealership, Ray, by far was the best service advisor I’ve ever had. He is honest, transparent, and genuinely cares about all of his customer interactions. He has a great reflection of the pride within this dealership. And serves as an example for many others in the department. He definitely set the bar high.
Great work. Took good care of me and my car. Would definitely recommend you to my friends. I will be back for maintenance
