One pattern I have seen in the UK is temporary manual car washes operating in former gasoline stations. Firstly, the location, visibility and site layout are obviously perfect. Secondly, the old brown-field gas station has sludge-filled underground tanks that cost a lot to remove, and do a full environmental clean-up. There are long delays to wait for a deep-pocketed developer, or for the site value to rise. In the meantime, lease it out to a bunch of enterprising migrants (in UK, often E.Europeans).
