1931 Duesenberg Model J Murphy Coupe –Â $10,340,000
Duesenberg’s iconic Model J was introduced to universal applause in December of 1928. E.L. Cord, who had acquired the company two years before, had directed Fred and Augie Duesenberg to design ‘the world’s finest motor car,’ and, by most measurements, it was exactly that. The Lycoming engine was built to Fred’s design, and featured twin overhead camshafts and four valves per cylinder.
