They were wonderful in getting my Ford Edge back on the road. We ordered a rebuilt transmission directly and had them install it. There were issues with the transmission and warranty parts had to be ordered. They took care of it all. They were always friendly. The pricing was reasonable and we are happily back on the road. Good Job! and thank you!
