Don't know how many were produced(consensus says but a handful)but in the past 10 or so years of ownership have not found proof of another still in existence or any that went to the bone yard.......1965 Dodge Monaco 426W with a 4 speed. As far as any one can tell it may be(but who truly knows)the only one left in existence. Have the Chrysler Historical docs to prove she is the real deal. Still waiting to see proof of another...... Valuable? To some maybe,maybe not. Rare....probably in the top 5 or worst top 10 list for rarity.
