No, you are incorrect there.
Various polls have ALREADY been conducted in the US and Lexus has always come up tops re brand impact. ESPECIALLY in USWC (west coast) polls.
And that same result has been repeated over a few years already. Lexus number 1, for the Americans, by the Americans.
Go search / read US survey results before you make sweeping statements like this.
And where is BMW in the US list? Its some way down the line.
Can't recall if Merc was higher on the list though.
And that's brand image only.
Reliability polls constantly put Lexus in the top 3. And this applies not only in USA, but also in the UK and continental-Europe surverys too.
