That's a really nice bike.
The Panasonics are not all that common ( at least not around here ) - but they are very well respected, and sell easily.
The chromed frame and leather saddle is a big plus, so I think $300 is a logical selling price - if road ready and equipped with pedals. Maybe $200 as-is.
- The Pletscher rack, IMO, looks a little incongruous on this bike, so I would sell it on eBay, and it could bring another $40 or so.
