but anyway, I think it can be fixed , some heating to put things in the right place, some plastic or fiber glass and some paint and good as new
psst, where is the speaker ?
If the rocker panel is all that's involved a proper repair will involve cutting out the badly bent sheetmetal and welding in a new piece from a donor car. I'd get under the car and check the frame rails, exhaust, transmission crossmember etc for damage.
