Thanks for the Diller tip, but I've already researched into it as much as I can without going to see it in person.

As for the bumper sticker, they're not trying to get you to talk to them literally. I'm sure it's a cultural statement whose intent is to contrast physical materialism with philosophical eudaimonia and "inner richness". Thus, you're more likely to see it on an old beater than a brand new Mercedes.
