Have we not learned our lesson about "German engineering"?
In my opinion, I would take the $50k and buy a nice used Japanese luxury car. I'm a big fan (granted I'm partial because I had one) of the Infiniti Q45. Or at least go for the big BMW if you really need the German stamp on it and a little bit of handling fun?
My apologies for giving you a vote outside of what you have asked... I guess I'm just a little anti-German right now... Maybe too much German beer or marsupial turds in my coffee over the holiday?
