Auto Motor und Sport called this story “Which sedan is the better choice?”.
I threw Google's translation bot at the page - but it's almost impossible to decipher regardless. I think I managed to 'pry' some sense from Google's translation of the article's last paragraph (but this is definitely NOT an accurate translation - I dropped a number of sentences and references). Here's their conclusion:
The 7’s imposing looks is a status symbol and therefore the justification for its high cost. The strengths of the 7 series are skillfully combined with the 5 series graceful lines which BMW's flagship car lacks.
Hopefully I did't botch it too much. Maybe a German speaking forum member could take a shot at it.
