Can anyone tell me how to fix this? haha

 

a bottle jack and some 2x4 blocks will help with most of the damage. after that it's just a matter of how much money you're willing to spend on tools and filler.

 

Body shop would yield the best results.

 

maybe, but that would take all the fun out of it.

 

the trusty ole BFH<-- ("big fu&%in hammer" for those of you who dont no)
would yeild the most entertaining results in this adventure
that whould get your portions of your car in a close vacinity of were its suppost to be
from there use a smaller hammer, some flat block of metal and a bit of imagination to get the metal as flat as possible, and to get ur curves and corners as close as possible
from there comes some body puddy and lots of sanding
prime
paint

at least thats how id do it

the one thing u gotta remember with things like this, is that if your not a profesional that has been doing it for 80+ years then it will be danm near impossible for you yourself to get it perfect, so go for "as close as it will get"

you could also try a whole new rear quarter panel?
