Apparently Audi has had this billboard advertising the new A4 up for months on Santa Monica Blvd in L.A.  The ad challenges BMW with an image of the new A4 and the pull-out, “Your move, BMW.” I know that comparison advertising can be very impactful, usually because its easy to remember the negative connotations, but the joke is usually on the antagonist, as seen here. After some months BMW responded, raising up a billboard across the street advertising the high-performance M3 and the word “Checkmate.” Finesse! But is this the final match or will there be a part 2 of this feud?
