The info may be flawed a bit, these are UN vehicles brought back by Pak UN mission units. One thing about them is that after being inducted into UN, they were able to get the much wanted parts, held back under sanctions.
From what I have seen of these vehicles, they have been in sound condition, but then it all depends on how long they have been kept before disposal.
The lot of UN vehicles auctioned was based in Malir and they disposed them off last year and then in May this year.
I shall continue with my duties, even if I'm too old for them 
There's been no UN security force in Afghanistan, EVER !.
