We are NOT here to talk you out of such a frivolous purchase, but rather to push you into it.
I would say $9k is a LOT for a car with 200k kms. I'm not suggesting you want to be that dick who lowballs, however in this case, having a talk with the guy about how expensive it is, and offering maybe $4500 would be in order. I mean the worst he can do is say no, right?
