I talked to Rudy (who knows all there is to know about a 2007 black base coupe) and he said I don't have filters. However, I'm meeting him and others up here at Lions Tap this Saturday, and I'll ask him if I do, indeed have cabin filters. I agree, that the pine tree in the roadster might work, but there simply is not enough room in the coupe for one! I'll keep hitting the "rest" button after I park the car.
