1954/55 Austin A40/A50 Cambridge RVF642
A survey of a long-empty house in Norfolk unearthed this and the old van in the next shot along. RVF642 is a local plate but doesn't come up on DVLA or Cartell, suggesting it's been off-road since at least 1980. It is though that this car was parked in a building, which has now collapsed.
In similar vein, one of my colleagues found a somewhat more intact Farina-type Cambridge/Oxford during the week.
