1981 mirada v8

Hello members,I'm new here and a mopar owner(challenger) ,I have an opportunity to purchase a 1981 dodge Mirada cmx,2 barrell, after a little research I see only about 53k were produced from 1980-1983, does this make them collectable? Are parts an issue? What should I be looking at to make sure the vehicle is worth buying?any help or advice at all would be helpful,it runs but is not road worthy, what's it worth ?thanks for your time
