LOLz!
You had to bring Acura in didnt you? Why because it is 'Honda's Premium brand?
As for the achievements of Lexus, YES they get the credit BUT the achievements of Merecedes are way more innovative. Mercedes started to give Automatic transmission when Lexus didnt even EXIST. So if they have refined that technology to some extent then it doesnt makes Lexus any better then Mercedes.
Japs are way ahead in technology and perfection.Some facts for you
Lmao!! In CHEAP ECONOMY saloons YES!! 
A lexus ls hybrid costs more than s class hybrid
So S Class is another target of your fanboy'ism?

Who's the daddy now? 
A lfa costs more thn a sls amg
Exactly the only reason of its faluire!
And this price tag is only because of the 'time' taken to develop a single sports car by a JAPANESE econ car maker TOYOTA. 
And it was revealed that until Lexus sells around 200 cars they WILL NOT get any profit out of it! 
p.S
Show me a single review where LFA is sought as superior to its European counterparts.
A isf costs more than a m3
