This is a match up for the guys here!  I'm partial to the Lexus, probably because I own one, but even I realize that Lexus is good at luxury and not so much at performance.  The good news is that Lexus DOES have the pursuit for perfection and they continue to improve, year after year.  The Lexus GS 350 F goes head to head with the Mercedes E350 and the BMW 535i.  How does Lexus do?  You decide...
