Soory to see your car like this
Claim on the insurance, its why you pay for it... Actually NO what am I talking about DO NOT claim on the insurance, that way my premiums wont rise
IMO the shell isnt fixable, not ideally anyway...
In this pic you can see it loooks like the door sill is buckled...!!
I would suggest its ben quite a bit offroad and possibly has more underside damage than above.. judging by the missing bodykit , lumps of mud etc..
