Well considering that Kleissl has owned the car since the 1980s my statement 'recently' is very accurate my friend. I own a 300SL and know what I am talking about when I say Kleissl is the foremost expert in the world on 300SL. He is the ONLY one that does nothing else than 300SL. Kienle does all classic mercedes and Paul Russell does other cars as well. These three are considered the best, but the focus of HK only on 300SL puts him in another league. I bought my car from him and so I can speak from experience. I stand by my statements!
