I agree with tracelifter, don't make a crazy lowball. Not if you really want it. If you're honestly gonna walk away if you can't score it for some wild under-market price, then go for it, what do you have to lose? She can hang up on you and life will go on. But don't say "$2500 ... oh wait, I meant $5000".
Unless it's just TRASHED and utter garbage the reality is paying under $5000 for a routed AFM is a good deal these days. For better or for worse.
