A Car with a Leitmotiv?

Alex Ross just used his The Rest is Noise blog to put up a post with a photograph of a model of Benz automobile produced between 1902 and 1905, which was given the name "Parsifal." This includes a hyperlink to a Web page (in English) on the Mercedes-Benz Web site. Unfortunately, that Web page neglects to say anything about whether or not the design included a cupholder for the Grail.
