How much money do you put into a car?

I love it, but I know I've got about 10K in it so far. Am I done? Nope, still got another 5ish to go before it's where I'd be fine not touching it. But then, at that point, I'd probably find something that I'd want to change on it. So it'll be a never ending cycle.

Right now, I want a new wiring harness, new torsion bars, new transmission (4 spd od or 5spd), new headliner/vinyl top, new stereo and speakers, Eaton truetrac LSD, a new intake, distributor, efi. yeah, I think that'll do for now.
