Carl J sends us the 1966 Duesenberg Model D - a one-off luxury prototype created in an aborted attempt to revive the legendary American marque.  The project began in 1964 - led by Fred “Fritz” Duesengerg (son of co-founder Augie Duesenberg) alongside a number of investors.  Duesenbergs had been a favorite of the well-to-do until the company ceased production in 1937.  With hopes of reviving the brand and marketing the car to celebrities - and whoever else could afford one - the Model D was unveiled in March 1966 in Indianapolis. The car garnered around 50 deposits from prominent figures like Elvis Presley and Jerry Lewis. However, corporate financing collapsed before production could begin, leaving the single prototype roughly 95% complete and ending the revival effort.
