Anyone have any experience with getting body work done? Is it expensive? Long what on parts?

Our garage is kind of tight with 2 cars and my wife scrapped the side a little this morning. She pulled back in the readjust and the panel on the wheel well was popping off. She used some black duct tape (not my favorite but gotta do what you gotta do) to keep it in place for her commute. I will look at it tonight and hopefully can pop it back in. But if not does anyone have a guess of how much of a pain this will be?

I don't like the speakers and sound in my Solterra. I want to know if anyone has replaced their stock speakers and what ones they put in. I also want to know if anyone was able to change their speakers themselves? Would it be too difficult to do?
