I bought a couple of them and parked them in different areas of the city to make it easier to reach any location using the subway + bike combination. I choose the ones with flaws that would deter normal buyers but relatively easy to repair, or with a damaged part that I'd replace anyway. I asked a local repair shop if it's fine if I ask the seller to send a bike directly to them and they happily agreed. So I look for an occasion, buy it, they ship it to the repair shop, the shop guy calls me and we talk about what to repair/replace, and in a few days I have a nice bike that will last many years with proper maintenance without spending a fortune.
