the ineffable allure

just got the latest issue of STEP magazine and there is an interesting article about automotive designers ("a breed apart"). In the introduction there is this paragraph:

"Car buyers want performance and safety, but what propels them far more than anything else is the ineffable allure of the new car, the emotional rush...that which makes it call out to the human heart and appeals to the human yearning for beautiful form. This is the realm of automotive designers, and it is where they find their greatest challenge."
