Well lets see 5 years ago I paid like 15kish for it. I can tell you I haven't put that much into. Even though I modded it that was a decision I made knowing it didn't add value and if I was ever to get rid of it I would demod and return the car to near stock. As far as repairs it hasn't needed much...new battery, master cylinder, starter, brakes, HB, and minor AC work. Things that were changed (optional)..water pump, CPS all changed during cam install to avoid future hassle. Oh and I need new rear struts here soon.
It was all worth it to me, parts have been rather cheap compared to other cars and even after owning the car for 5 years I still enjoy driving it.
