Three photos, two questions. First, can anyone tell me what the little inverted dome is that's stuck to the roof of my F40 interior (1st photo)? Is it a dome light with the bulb broken? A sensor of some kind? I can't figure it out... Also, notice the cracks around the drilled holes in my front and rear rotors (2nd and 3rd photos). How serious is this? My dealer pointed them out today - I was surprised that the dealer who did the PPI on the car when I bought it last month didn't catch this. Were the stock F40 brake rotors drilled AND slotted like this?
