2009 Mercedes-Benz CLS First Impressions
Vienna, Austria - It wasn't the symphony of Strauss or the romantic notes of Mozart that floated in the Austrian air but rather a unique purr coming from the new exhaust system of the 2009 Mercedes-Benz CLS63 AMG. Or was it the CLS550's more subtle sound? Anyway, we were in the beautiful capital of Austria to put the German brand's newly redesigned and gorgeous 4-door coupes to the test.
