Mercedes runs their Sprinter line with the Mercedes star on the front. I know some after-market modifications can turn these into really nice RVs, but they're mostly in the "work van" category. In Europe, Mercedes doesn't really have the same connotations of luxury/aspirational purchase that it does in the US, so maybe that explains the willingness to slap their insignia on a work van. But nobody in the US seems to think Sprinters dilute the perception that other Mercedes are a luxury.

Edit: ugh I see at least two others made exactly this same point while I was typing my comment. I guess it shows that it's a valid one...
