It not suprising that Lexus is taking a new design direct. Just look at the design of the S-class(ww140), that has probably have got to be the most copied design ever. Toyota, Lexus, Honda, Kia and several other manufacturers has copied that car so much that it has resulted in the newer MB cars looking like Japanese one. The old ww140 design is a milked cow and even MB themselves have moved on..
