I sold my Aston Martin DB7 to a really nice guy who lives near Pusan and am trying to help him find a good mechanic who could look after it, do routine maintenance on the car for him down there. 

Does anyone know a good mechanic or tuning shop that can take care of unique or specialised vehicles like my Aston Martin DB7?
