I totally get it. I bought an Aria Legend Jazz for £60 from someone who got it, played a few times and forgot about in a cupboard. I put new Wilkinsons in it, a Fender Himass bridge, new pots and electrics, added a Fender waterslide decal for the hell of it, fine wire woolled the neck and fret ends for that smooth 'played in' feel and because now it's essentially part of me it's my go-to bass indoors and more often than not my live weapon of choice. It's hard to explain but because I put 'me' into it I could never part with it.
