I was looking at an ad for a ‘01 Boxster S and they have the retracting spoiler up in the pictures. IDK if it’s broken and stuck in the up position or if the Boxster S has a button the lets you put it up when ever you want.
Either way this one looks like a CD Tray that got stuck while closing.
Oh yeah you can pop it up when ever. Skip about the first minute of the video.
