Bugged by the Lack of Good Grammar in Ads

I know,casual conversation trumped correct grammar long
before now in commercials. [Winston tastes good like a
cigarette should is a classic example.] I can even
rationalize that the writer or client really wanted to
link the word like to the brand.

A case in point now is Ford's use of further instead of
farther. I can appreciate the play on words and the
corporate side message that Ford goes further or the
extra mile in quality, advancements and engineering.
However, when attached to a brand message directing
the consumer to go further,to me it looses something.

As a consumer, I do not want Ford to take me further,
I want them to take me farther, which I consider to be
the bigger benefit.
