I think you are right tho I do think a pretty girl can be good.
One of the most famous and probably successful advertising programs was “The Dodge Girl”. They picked a really pretty girl but she was an unknown.
Come on you marketing curmudgeons; there are Dodge, Ford, Chevy, Jeep, Toyota, Honda, Pontiac, Saturn, etc, girls. Every young man’s dream is to own a sports car and pick up beautiful girls (or have you old guys forgotten already).
Don’t remember the Dodge girl. (Then again, I am a woman.)
I suppose having a beautiful woman creates a lot of buzz and makes people — well, men, anyway — look at your product. But, seriously, is someone actually going to plunk down the thousands for this car because the manufacturer presented them the opportunity to ogle a comely lass?
Perhaps such a ploy would work for a pack of gum or for some brand of a product that one buys anyway, but a car?
