You won’t find it until your foot goes through something or something falls off. I had a 1990 defender 90 which was 8 years old and the bulkhead was invisibly rotten in various places. That got very expensive very quickly. A friend has a more modern 110 that’s only 6 years old and has the same problem.

This is not an issue in some areas and dry climates as a rule but in the UK it sucks owning one.

I don’t own one now. I drive a little French go cart then I use my legs for off road. They last longer, don’t go rusty and run on dried fruit and sandwiches.
