Does advertising like this work on you? BMW’s use of “guerilla marketing” is the talk of the town… well, at least it’s the talk of CNN’s American Morning. The 1-series is already being marketed in the mainstream on the basis of its fuel efficiency and 2002tii heritage. Does it matter whether BMW’s Rampenfest campaign works or not? After all, production costs were a fraction of the typical cost for a 30-second TV spot. Not only that, but the Rampenfest clip spreads like wildfire – at no charge to BMW. As evidence, I submit its presence right here on GoodCarBadCar.net.
