Volkswagen US podcasting for Motor Show

Volkswagen US has jumped on the corporate podcasting bandwagon on the occassion of the Detroit motor show. The VW podcast site is featuring entertainment with various Detroit based bands, consumer insights with the Detroit GTI enthusiasts, on location documentaries of the fair, and testimonial interviews from VW and Car Connection.
The podcast links for iTunes and XML are only accessible after entering your eMail address, which is a mistery to me. On the site teasers of the podcasts are available only.
