Ray, Although Delorean may have taken his idea for the Grand Prix from the early Dusenberg of 1932, I think it the Exner design of the 

early 60's (attempted revival of the Dusenberg name into the car market) that he definitely took ideas from.

Interesting story of Dusenberg's attempt to come back,twice,once in the 60's and again in the late 70's.

Design-suggestion  made in 1963 for a Duesenberg revival.

1969 Pontiac Grand Prix

The Model J was a handmade work of art.

Hence the old expression, "it's a Dusie!"

 

There used to be some great American marques, like Auburn, Peirce-Arrow (from Buffalo). Those coffin-nose Cords were sort of the inspiration of the Olds Toronado.

When you think about it, GM was in an unassailable position in the market. With all that critical mass, 5 car divisions (more if you consider the specialty Canadian hybrids   ) It gave GM the ability to shuffle various stuff to different divisions. I mean the 1966 E-bodies were the Toronado & Riviera. One was FWD and the other RWD. Meanwhile running high-speed cameras at Camaro leaf springs lead to the implementing of staggered shocks. I guess mass production and market share could fund a lot of development.

 

how much could that 1932 Dusenberg be worth ?
