The rubber floor mats have been removed. I double-checked for anything else that might be hidden in the car and contributing to the smell; the car was/is basically empty, like a showroom model.
I put my nose to the floor mats and did not detect an obvious odor, certainly not the odor I am concerned with. So, it will be interesting to find out if some sort of volatile compound has been escaping from the rubber and infusing the air with the smell.
I bought a black rubber dead-weight mallet from Harbor Freight many years ago. It still smells like an asphalt plant.
