Wow!
When I bought my very first Cuda back in the 70's I noticed that. I was a kid and thought nothing of it. Later, when I bought another Cuda some 20 plus years later, I opened up the door and smelled that very same smell! It instantly reminded me of my very first Cuda 25 years ago! What is odd is that the smells are the same, and that it still smelled this way 25 years later in a different Cuda. It has to be the materials that the factories were installing. It is a very distinct smell that I have noticed in other Cudas.
I have never mentioned this to anyone before now. It's not you. You are smelling what I have for almost thirty years!
