I recall his last "seminar" at Carlisle a few years back ('05, I think) ... This one couple wore his ass out complaining about his pompous attitude, and the time it had taken to hear back from him on their car. It had been over a year at that point, and they were there to find out why, not just ask general hobby questions....It was in front of the whole audience! Once they opened the flood gates, many others in the audience let him have it too....Man, was he embarrased! Never saw him at Carlisle again.
His services are an asset to the hobby, his business model and poor customer service ain't....
