I haven't seen the advert and therefore haven't heard said drippy accoustic version, but I do remember a couple of decades back Mercedes used (the original of) Janis Joplin's "Oh lord won't you buy me a mercedes benz", thus displaying unforgivable but unsurprising lack of self-awareness. Quite possibly drippy accoustic version of "Born to be Wild" is more appropriate to the actual vehicle being advertised? Which is more of a reason to take the advert off the air and the Wankpanzer off the roads than to approve it...
