Before grinding, get a screwdriver and poke the front floor pans, along the sills, inner wheel arches, bumper attachment points. Also check round fuel filler neck.
With that much floor pan rust, you're almost certain to have widespread problems. It really might be bye bye time. The floor pan is not a million miles from the rear seat belt anchor points, the inspectors might be doing you a favour.
Mines started again on the underside of my punto - its time to get a grinding and repainting!!
