Luxury German car brands are battling it out on billboards in California.  Until now, the wars have been contained in their home country, but Audi broke what may be an unspoken rule and put up the above billboard in Santa Monica touting its A4 line of cars and challenging BMW to respond.  Not to be outdone, BMW posted its newest 3 series vehicle on a billboard right across the street.

The brands then hit the social media circuit to continue to try and outdo the other, which apparently resulted in some photoshopped pictures and some funny tweets.

But for now, it seems that Audi had the last word.  They replaced the above billboard with a new one that tells BMW “It may be time to check your luxury badge. It may have expired.”

BMW has yet to respond and change its billboard, but maybe their killer response is in the works or they are looking to expand the war to other places, like Atlanta, GA.  To see the photoshopped pic and the entire article, click here.
