Or rather not upgrade, but get some repair parts that the bot herself (when she already has some limbs, probably) could fix up, one wear level at a time. Or maybe combine two “thrashed” limbs to make a “worn” one, with the limbs needing to be the same, and the final color being one of the original’s. Or add a “mosaic” type of color, which is just plain ugly, and needs another 5k or so to recolor, and maybe 50+k to mkae it the chamelion thing.
Since our Anon is kinda described as having gotten only a general education highschool diploma, I doubt he’d have enough mechanical knowhow on how to do fix everything himself. And the bot could be given a bit more agency of sorts in actively providing for him (besides the sex streams)
