The poor soul was a '76 1800cc sedan. She was to be a donor for a Clubman project that is yet to materialise.
In my opinion, the reasons for rust in the base of the A-pillar are:
1. Lack of paint/finish on the internal structure. There is also a complete absence of seam-sealer.
2. Poor quality steel.
3. Bad design. ie: lots of water traps, coupled with many pieces of metal in contact with each other. IIRC I counted at least 5 pieces of sheetmetal all terminating in this area.
4. Crap from the vent plenum adds corrosive sap etc to the mix.
5. Crap off the front tyres ends up in the same place as in para 4 above. Pull the inner splash shields and take a look. This cavity extends all the way up into the A-pillar
6. I also believe this area suffers quite a bit of mechanical stress from body flex, adding to the onset and vigour of the corrosion.
This rust begins internally, so by the time it manifests at the base of the 'screen, or up the firewall behind those triangular bonnet-stop panels, it's ALWAYS pretty bad. Whenever you are inspecting an Alfetta based car, stick your head into the engine bay and look back toward the base of the pillars. Any lumps here mean WALK AWAY.
Everyone blames moisture getting under the windshield gasket. However, once you see how the area is constructed you see that this is of minor importance. Water does sit in this area, but a little rust in the outer skin alone is quite simple to fix. Besides, the same problem appears on gasketed (GTV) and glued-in (GT) screens with equal regularity.
