Except for its lack of storage space for tools, parts, & etc., this one has Ken's name on it.  Especially as it is Michigan, where the hell Mattawan is located.  Sounds like the upper peninsula but I didn't look it up on maps

Too bad this one isn't in Davis CA.  BTW, the Trabant sold for a mere $6,100.
