Thanks everyone for your replies.
In the end the logistics of getting it to a specialist got too difficult.
I thought about getting an on-site inspection from the RACV or one of the independent companies, but wasn't convinced of the value seeing they wouldn't have any specialist knowledge.
Ended up just spending an hour or so giving it a thorough going over myself and then taking it for another test drive.
The end result is its coming home with me once the RWC is done :)
