You're in NZ aren't you? There used to be a gazillion of those things over there. They were a popular $1500 student car. Quite a few got used for the undie 500. They are probably considerably more desirable now although I imagine still quite cheap and a lot are in bad shape.
There was a guy turned up at a local AutoX last year in a metallic red carib 4x4, didn't look much.
When asked in scruiteneering if it had a current WOF (MOT equiv) he said yes, does it matter if it's supercharged?
It seemed to go good i think he had engine swapped it with a supercharged 4AGE from an older MR2
