This is definitely an Australian car, will check the stamped numbers on radiator shroud and bulkhead.

What style windows are in the doors - sliding or wind-up?

Thanks Winabbey and others.
I am aware of most of the points you have made.
This is definitely an Aussie Cooper S, I know quite a few of the distinguishing marks etc, has wind up windows, drilled holes in gutter, 120 mph speedo etc etc.
It obviously has a dodgey ID plate on it, which will diminish the value of the car considerably.
Seems the car was imported into NZ in 1991, and serial number on plate is on the NZ rego documents, so false plate probably fitted before it came.
It is a genuine BMC (Aus) plate, but hand stamped from the front, not the rear as factory fitted.
There is no way of finding the true chassis number, so it is what it is, a car with a false plate!!!
Thanks again for your help.

All does not look kosher with those photos. The ID plate is for an Australian Cooper S and has car number YG2S4 752. The number on the radiator shroud has a finger in the way, right where the car number prefix is. What is stamped there? The car number on the rad shroud is way too high for an Australian Cooper S. On an Australian Mk2 Mini YG2S should be one stamp, with 4 a separate stamp, then all the body number digits as separate stamps. It would be worth checking the scuttle drain chanel, at the rear of the bonnet aperture, above the wiper motor. You might need to sand away the paint to see the numbers. There should be M2/06 then the body number, which should be approximately 500 less than the car number. So, if the ID plate is correct, then the body number should be somewhere around 250, give or take a little. The single most important stamping on the car, if it is an Australian body, is the M2/06, as that shows the body was originally made for a Cooper S, with all the associated brackets, etc. If it is M2/04 or M2/05 then it is not a genuine Cooper S.

Yes, my mistook. No M in the Mk2 code. So, it is likely to be a reshelled car. But if it ever came back to Australia it would not be legal. The problem is, as a reshelled car, it will be sold in NZ as the original car, just like in the UK, which is a can of worms that people have debated about for millenia - see Ship Of Theseus on the interweb.
