fellow car-addicts!! i need your opinions here.

My family has a mid-80s Corona and I am considering restoring it. it needs major body work and a new paint job.

Just some questions: is it worth restoring in the first place or should we just sell it as it is dirt-cheap (which means it could go to a junkyard? i also think its very underpowered because it weighs a lot. whats a good engine to replace its stock machine?

thanks all to future replies
