Its all relative.To how much money you have and are wanting to commit.Burnt out pop stars have blower Bentleys as runabouts on their estates.My brother took me to see a large house being extended,and there were cammy Nortons and Velos in alcoves on the walls.Mounted and stuffed as it were.My old boss has five Vincents,and goes on $ 250,000 world cruises.He s too old to ride.I have bikes that cost $50 or less 40 years ago.Some restored some not.I refuse to spend silly money on plating,or anything else.In the rarified atmosphere of prewar BMWs ,100,000E is probably a starter.So I dont go there.Regards John.
