i dont want to get into this too much
i think what the chief was saying bmw is the leader as in the
chassis and driving expereicne
lexus is more focused on making a chassis that is more driver orientated
not matching bmw 3's engine to engine variant to variant
lexus is more focused on providing a car that is catered for you
where bmw is more of a customised car to your taste which ends up costing abit more than usual
