Brought my M5 to 3 different BMW dealerships. (Hendrick) (Critz) (Hilton Head) as well as 3 different Indy shops (European Road and Racing) (Buckhead Imports) and another shop in SC. Nobody could figure out the problem with why I was getting limp mode on my car for 3 months. Tom the owner figured out what was wrong with it within 30 mins. Told me what he did how much it would be and kept me informed the entire time. All work from then on out I brought to him. The amount of knowledge he has about these Beamers is insane. A true expert in his field. Would give 6 out of 5 stars if possible! Highly highly highly recommend
