I dunno, it just seems to me that there's no reason to charge players money for it. I mean, a street samurai is probably wearing armor worth tens of thousands of nuyen, total, and it's okay for that to be abstracted enough to not worry about damage at all. Normal wear-and-tear on stuff is either generally ignored or handwaved to be included in Lifestyle, which is a good way to handle it.
Since things like drones or vehicles need to have damage tracks, it makes sense that you can't just ignore the damage they take entirely, but I think it would be good to just abstract it to "for this much damage you need to buy a Automotive Mechanic Shop, which has X uses". Like a medkit, at most. Or just include the cost in Lifestyle, and add a "garage/repair shop" lifestyle option.
