Martacus,
The kit was released as a standard MM2/RW vehicle, no lower nose, semi-stripped interior (still had carpet and doorpanels), cutout tail/trunk with fuel tanks. One version available had a standard chromed plastic blower, the other did have a diecast blower. I don't know about any other goodies, but I was only able to get the Standard kit. Detail is really very good, it looks like a Ford product in general layout and an Aussie Falcon in particular. No under hood detail, but has a can of dog food!
A/FX Resin had a conversion kit to turn the RW version into the Mad Max version (front valence, trunk and all). I heard rumors over the net, which are subject to much scepticism, that tha Aoshima kit would be redone as the first movie version, but I have not seen this come to pass.
The resin models I have seen are close, but most are not really too good in my opinion.
To scratch your own, you could use the Revellogram 1970 Torinos, redo a lot of body sculpting, shorten the tail/trunk some, add an AMT reissue 71-73 Mustang Mach 1 NACA scooped hood, a little styrene, lots of patience, and get to a good Interceptor. Or find the Ao kit on Ebay or at a store that couldn't sell them off (what'en da heck isdis thang?!?).
As a resource,

has pretty much everything you could hope for as far as info. And remember, the cars were totally stock, publicly available rides in Australia when the movie was made, so Google'ing the web and images will net you lots and lots of pics of the stock cars and the parts that went into them (like the nosepiece, blower and scoop,blower switch, etc).
Good luck.
Tom
