HOLY F*&^ *cries*
sorry to see this man,
you'll have to bash it out the bottom of the door frame a bit then fill it with some thing good, cant remember the stuff they use (you see it on pimp my ride a bit with the dinged up cars)
the guard CAN be saved, mate those panels are flimsy, just get out off the car, and take it to a beater, they'll beable to beat it straight, then fill it again or get a new one and cut the flute out?
so what exactly happened, how did a bike slide into you? your fault or his?
sad day for modified cars
you can get the skirts recast easy from the looks of it i dont think the skirt would be repairable
id say $500 if u did it yourself ish, but for a insurance quote id go with $1500ish
