Convertibles have always been desirable. Production cars
optioned with the biggest engines were always rare. Combine
those two factors and it is sufficient to conclude that the
big-block drop-tops are the pinnacle of collectability, as
they are both desirable and rare.
Collectors agree that the minimum
five (6) criteria for gauging rarity to include: year, make, model body
style, engine and transmission. Paint color, trim
and other options are also important when building a world-class collection,
however, they are not baseline criteria.
This is a list of
the rarest and most desirable convertible muscle
cars ever built on an assembly line, meeting all federal
safety standards and having the intention of
being sold to the public.
The Mopar 'Hemi
cars all had dual 4bbl (8v), however, only one other
brand convertible received dual quads atop its 7-liter big
block..... the 1967 Shelby G.T. 500 Convertible.
