Adapt or die

The main mystery I'd like to solve is, why would Chrysler allow a million dollar + tool to sit idle and not produce any parts?

Chrysler has been dead for decades.
Daimler gave zero about MP or the obsolete junk we run
Cerberus gave less that zero
FCA is making money tuning old (Gen 3) Hemi motors to staggering levels in aging, but capable old chassis, and (let's face it mostly) selling Jeeps and Trucks. Our old junk was never even a consideration.
That million bucks was written off L O N G ago and means nothing to the new boss. twocents
