What to do? tipped twice and rusted out

Okay here the story i had my 90 xj for about five year in that time i bet the crap out of it. Tipped twice (once on one side i fixed it, then on the other side but not as bad as the other one) frame tweaked, rusted out floor boards when i got it, bent and broken body shock mounts and hole thing is in bad shape should i try and fix it?

I got a 89 xj but it cant be registered got it just for parts


Any answers would be helpful?
