should I buy

It's not that she's not welcome. We welcome anyone. It's that we've been bitten many times in the past by the seemingly same old story. The burden of proof is on her. If she wants to come back and this is all legit, then she'll get more help here than she can choke a horse with. You can't blame folks for bein a bit gunshy.
Agreed, we've seen more than a few trolls of late, or possibly the same troll in different disguises, but the biggest difference I see is that the OP did post what appear to be legitimate pictures of the car in question, big difference from whatever that other one who claimed to be "inheriting a 440+6 'Cuda, buying a salvage yard, undergoing cancer treatment", etc. all in a span of a month or so.
I can see being a bit gunshy, but getting one's exercise from jumping to conclusions is grossly unfair.

Personally I do hope that she comes back, at least for some sound advice or suggestions. I don't think the car in the pictures is a terribly bad buy for the $$, it may not be the deal of the century, but if it's solid and has most of the necessary parts to put it together, why not? There are a few members that hail from Saskatchewan here, maybe someone is close enough and willing to spend a few hours helping her make an informed decision, I would gladly do so if I were in the area.

Just my .02.
