Look for rust in the rear floor (cargo area), thats a lot of miles on their salt roads. Will find some other info I had somewhere....
make sure its had the cambelt done (should of had a modification done back in UK, they had alignment issues and threw the cambelt off)
Check for rust around alpine windows (long oval ones up high). Bound to have the odd rust prevention feature underneath (oil leaks) Not hard too get seals replaced and believe it or not they wont leak (never had a drop from my 91 V8 I owned a while ago). Also round cargo area glass, waist seals on the four doors (run along the bottom of the window). Behind the rear bumper. Inside the front guards against the firewall. Not such a big problem with NZ new ones, but being that its from UK....
Search the net and land Rover Forums, theres bound too be other things..
They are not as bad as people make them out too be (those that moan or bitch about them have usually never owned them

)
