You can't post pictures until you have 10 posts, I think.
Rusty brake discs aren't a huge deal, especially if they're 65 000kms old. Although if they're extremely rusty, it could be an issue. Hard to tell without looking at the vehicle, or seeing pictures.
My advice would be to take the vehicle for a Pre-Purchase-Inspection at a trusted mechanic if you any doubts at all. Should cost you about $100 - $150, and they'll let you know if there's anything wrong with the vehicle, what work it may need not too far in the future, or if everything checks out.
