Interior trim

Hello All,

Just wondering as is my first car (1990 JDM Da9). The dash is cracked and some of the interior pieces are scratched up, stained or otherwise damaged. Is there a way to restore these? Purchase new ones? I am located in Australia and i only know 1 gen 2 owner so they arent exactly as popular as they seem to be in other places.

Any help is appreciated!

Can you upload some pictures of the damage?
