When to say when with a project car....

Just because you can't do anything with it right now doesn't mean yo need to get rid of it. My Barracuda has been an 11 year work-in-progress. I've gone years at a time without doing anything to it but driving it on weekends. If it's the car you want, and you don't absolutely have to sell it because you need money, I say hold on to it and work on it a little at a time when you have time and money.
