It's hard to think of many businesses that require lower capital investment and maintenance than a car wash. The ones I see in my city that look like land banking are a big plot with asphalt covering it (don't even need to mow lawns), a few awnings with some plumbing for hoses and soap and other gear, and nothing else. Even a laundromat would cost more to set up.
These car washes are not simple, nor cheap. They aren't talking about places where you wash your own car, they're talking about the increase in automated ones.
