it was 450 in so-cal, did a great job
i had the same thign happen to me but it was cuz some bitch in an suv opened her door on me. i found a reputable place and tey did a great job

 

one brand new fender should cost no more than $300 for a bodyshop to order...

 

I took it to the bodyshop, they said I dont need a new fender and it will be done tomorrow morning. It was $531.

 

That'll buff right out.

 

Couple of grand easy. I had something similar happend to my G35x.
With silver or like colors, they have to match. I ended up having to use insurance.

 

so basically they just sand it and use those wat u call those things?..and cover the dent,then repaint ur fender. the process is a easy job for a professional to do...but after they done look really careful the paint job...see if they have any paint holes/ bubbles or paint is very wavy..then there might be a problem...

 

That is why I DO NOT DO GARAGE!
But your situation sux. Sorry to hear that.
