hmmmm well this makes it a bit more difficult.
There's a lot of information around in regards to the specific cars/motors you're interested in, but i have no idea of local emmisions laws or local modification laws.
The best information you can get will be from local people, who have similar cars.
Before buying a car, its important that you get all the information you need... it would be awful if you purchased a car , only to find out that you can't source parts for it locally.
Here are some links where you'll find some basic MR2 info, specs, etc.
MR2 links
Worldwide MR2 club listing
I tried the link for the Norwegian MR2 club, but it wasn't working. Perhaps there are some auto directories available to you which will have some more specific information about how you can contact your local MR2 club.
as for a Mazda Cosmo..... were they called something else in Australia? I've never even heard of them before.
