I have Peter's list. It goes from 9242 to 9250 (both in or from Australia). No 9245.
The car sure looks like a legit GT5. The chassis and engine numbers are correct. The wheels and mirrors are not original and there appear to be a few other mods.
I'd say $65k is a low number for a GT5 - of which there are but 110 left of 250 built.
As Joules indicates, the condition it's in will make for the range. If those pictures are current and it has already been gone thru and is roadworthy and updated it will be worth quite a bit more.
I know of a few 'stock' GT5's that have gone for $90k+. Each of the new owners then spent heavily on them.
