What is this worth?

I have a 1990 mercury cougar. I can't afford insurace on it because if college and the insurance company classifies it as a sports car. So it must go. It has 74,000 km on it. there is a little rust on the drivers door but before selling i plan on painting it and fixing all that. also the head unit for the sound system is screwed up. i'll fix that as well. Tell me what you think this car is worth? It's all mechanically sounds and theres never been a problem with it besides what i mentioned above. Also please include the currency that your thinking in... I'm in canada

Thanks
