I was stopped at a traffic light and while waiting, noticed that every once in a while the engine hood would start vibrating in the center. When I got home, I popped the hood and had a look at the center rib under the hood skin. I never noticed this before; but, on my car the hood skin is not attached at all to the center rib and in the middle (front to back) there is about a 1/8 " gap between the hood skin and the top of the reenforcing rib. The hood skin is attached around the periphery; but, is completely unsupported in the middle. With the hood closed, you can press on the center of the hood with you fingers and it will deflect downward about 1/8" before contacting the center rib. The hood was never damaged and there are no signs that the hood was ever bonded to the rib.

Are other people's 140s like this?
