The car was actually bought by a board member (XR34X) in 2007 from an import yard in Fawlkner - maybe if you can get in touch with him he could fill you in on what happened to the car. You can find his original post (car photos match the carsales ad - right down to the wheels) here:

I sent a message to the ad - it seemed too good to be true but might have been worth a look if it had known issues for repair (which would lower the price). But I got the reply about the sick daughter as well - makes no sense, medical bills usually have long terms of payment, an 8yo isn't going to be untreated for serious illness in Australia and you'd be trying to get as much money as possible wouldn't you?
The reply came from a different name than was on the ad, the name on the reply is actually an American broadway singer/actress, and I got asked for my location 3 times with no info about the seller location. None of my specific questions were answered, the reply seemed to be very manufactured - eg the car model was copy/pasted from the ad in my reply.
Don't touch it.
