Everything looked good until the old windscreen came out, got a call today to come and have a look, doesn't look good. the bottom plate/sill is rusted therough and is buggered, and to fix it good they will need to get a new plate and weld it in and said it would be "more then the cars worth", thats worse case scenario if its structually screwed, but if its not his gonna sandblast it and nicky it up. but he said it will probably only last two years and the rust will come back.
whats your thoughts? if you were in my situation or have been in my situation what would you do/have you done??
i really dont want to get rid of my baby, but i might have to

cheers all.
