Donnie was very courteous and helpful (but not helpful enough, I didn't want to have it towed there just to tell me what i already knew. Wasted $270) repairs were just a little too expensive for my taste, not their fault. Industry average. But just because of my cars age and mileage. I didn't want to pay that price. I still would recommend them. Though make sure you research your car and option for repairs so you HAVE options.

They were professional and attentive and gave me orher recommendation for another issue ( unrelated) I have. Great service & customer service.

I worked with Junior Rodriguez at the front desk. He kept me up-to-date on the full process & is very experienced in the insurance process “ Extended warranty extra care” The turnaround on my transmission was extremely fast (actual replacement of trans). My car drives like a brand new car, they even washed and detailed my vehicle before I picked it up. Excellent service thank you guys so much
