New 1.5 owner here. In cleaning the interior I'm unclear on which parts are metal and can tolerate a metal polish. Door unlock handles: obviously chrome, so they can be polished. Door pulls, the silver part: aluminum? Mine have tiny dark spots on them. Not sure how aggressive I can be in attempting to polish out those spots. Center console top surface: aluminum or painted plastic? Sounds like aluminum when I tap on it. Center console knobs: not sure if they are aluminum or plastic. Gear shift knob: appears to be aluminum. Gear shift shaft: definitely steel. Chrome plated or just highly polished? I think the latter. Wide silver tray (instead of a glovebox): appears to be aluminum. Pedals, brake and accelerator: aluminum? Forward wall of driver and passenger foot wells: aluminum? Thanks!
