I bought a used opel corsa last week and just noticed today a (pastic?) piece hanging off of the bottom of it. It doesn't look like it was screwed to the car (no holes or anything which would fit a screw) so it seems like its just "sticked in" there somewhere and come loose. There is another one on the other side which looks like its still in place.
Whats this, is it important, how do I reattach it properly?
