WSJ reports Audi's efforts to try and gain marketshare from the better performing European rivals.   Audi has increased marketing in an effort to gain marketshare during the down markets over Mercedes and BMW.  This seems to be working, and they are close to overtaking Mercedes as the second largest premium auto maker.   Audi has long been known for its ability to put forth great innovations and interiors, and lately are getting better at making a better Audi Suspension.  Some has been the result of work on Audi Control Arms, but there are still strides to be had.   Audi is notorius for basic parts failing like the Audi Window Regulator.  We sell hundreds of these, and they just dont seem to be getting any better.
