A couple things to keep in mind:
1. The British are not good at oil seals. Expect British vehicles to leak 90 wt unless someone went through some extra effort. Leaks comes with the territory.
2. The roads are salted during UK winters. That's why there is a replacement frame industry. Assume any 25 year old truck imported from the UK to have frame rust issues unless there has been a very recent frame replacement & bulkhead work done.
When looking to purchase a new UK import truck that is 25 years old or older just assume you will need to also buy a new frame & maybe bulkhead and figure replacement into your budget unless you preinspect the vehicle and find out otherwise.
Just a observation and suggestion
I was going to say the same thing - even my 2002 Discovery was leaking all over the place.
