I wish I could export all japanese E30 to AUS and NZ. ;-)
Low Mileage guaranteed.
Average 7,500 km per year is normal here in Japan.

But I have heard that there are restrictions for imports of used cars. What's the age it becomes cheaper? 20 years old cars and RHD? Is there any online info for that.

And many, many E32 750 and E34, oh yeahhhh
