Hi Doktor Tim,
I'd like to have you service my Syncro. Not that I value the DM(and the
resulting cost)so much but to see San Juan Island ! What's you DM labor
rate? Your statements reminded me of the following:
How many Kraut engineers does it take to replace a friggin' light bulb!
NONE - IF it was designed, manufactured, installed & operated to German
specifications !
