As most of you know, the concept styling was by Eric Stoddard who worked for Chrysler at the time. Brit Andrew Dyson modified the design in conjunction with Karmann engineering so that it could be built using various Mercedes-Benz parts. There was no actual prototype mockup car made (mule) as everything was done virtually. Karmann built all the cars under contract and they are now in receivership but will continue as a viable company (if the Karmann website is to believed). As far Chrysler parts that make up the content, I can only find the safety glass marked up as Chrysler specific but there must be something else!
