Self-Repair: Science Fiction

They were the first of their model number to be self-repairing, something that they saw at first with pride and later with great relief as more and more of their batch-mates succumbed either to metal fatigue or processor overload or--if they managed to have a good contract--they signed away their lifetime for the length of time it took for the new part to expire, by which time they needed a new part anyway. They had nowhere to get it except through the licensed store, and that was an expense that only warm-bodied owners could afford. They had no owner, and they liked it that way. They got junk parts when they hadn't worked in a while. Once or twice they'd even scavenged old processor parts from

Inspiration: deviantart.com picture, "Broken," of android bending over a clearly dead woman on the street.
Potential: High.
Notes: A woman has done some kindnesses for them, so they rescue her and use parts to fix her up. Not a romance. Think of Frankenstein, medical costs, indentured nature, corporations "owning" people, maybe becoming an android is in some way better for her. Metal mask, passes/does not pass as human? Thoughts.
