My friend Bobby sells used service vehicles. He is a good man and takes care of people. I've purchased at least 6 from him so far for my roof repair company. Bobby was paying $100.00 for a part for those vehicles from the parts department at a local Chevy dealership. We called Ryan Holly over in the parts department at Earnhardt Cadillac, and Ryan got him the same part for $40.00!! The other place was taking advantage of my friend. Bobby will now only buy from the parts department at Earnhardt. I've also purchased from Ryan before and I contact him whenever I need a part. He is a real pro who truly knows the business. He ALWAYS has answers to my questions and can get parts FAST. I've also taken my Gen 1 Hummer in for service in the service department there and I was VERY pleased. They really took care of me. I would not hesitate to do business with any division of this business, they really seem to have it together, but Ryan is certainly the reason I keep coming back, and why I recommend friends, family, and businesses.
