Bad news: the very next day, I allowed my fella to give the car a test drive, which went okay except that he didn't park it back in my usual parking space. And long story short, when I went to leave a little later, I misjudged the distance between my car and the tree behind it...and backed into the tree. There's not a whole lot of damage, actually nothing detrimental; it didn't even scratch the paint. However, the little part behind the wheel has come a little loose, and honestly it looks i could just superglue it back, lol, although I know I shouldn't do that.
I've circled the part in this picture where the piece came loose.

What should I do? Should I take it back to the dealership or try to have someone else fix it? How much do you think repairing that kind of damage would cost?

saves a lot of money that way....but again sometimes on a brand new car you'd rather have an actual FIX done...I didn't see anything wrong in your picture though so it must be small??
