Curious of my Subarus value?

hey yall. bought a 2006 subaru impreza outback off fb marketplace. at first everything was great. it looks like a great car. but it's been nothing but a headache. whoever had it before me just didn't keep up with maintenance. right now, i can't afford to fix it because it needs whole new brake lines. they're totally rusted out. would it be worth it to put it up on fb marketplace? what would a realistic price to ask for? (Aesthetically it’s in pretty good condition. Interior has no stains or rips. No visible rust on exterior)
