I'm sure the bulkhead was still fine, any reference to door pillar corrosion may have been the B pillar. When I bought it 15 years ago (when it was 10 yrs old) the B pillar had some rust that I had repaired straight away.
But the long list of failures were later rectified as it went on to then pass the MOT. However it was never MOT'd since, which is strange.
However the buyer did intend to use it on private land, moving trailers around etc. So the fact it isn't currently in MOT may not be surprising if they don't intend to use it on the road anymore. But to get such a long list of issues rectified would have been expensive, and ought to mean that the big problems now no longer exist, and it should be OK for the next MOT, but it never had one.
