Car ablution bazaar in the U.S

It is hard to imagine that all the cars in the United States, it seems that wherever you go there cars. These cars get dirty and then you look bad, so it must be washed and perhaps that is why there is an endless supply of people who want to enter the car wash business. There are many who find the car wash business to be a worthy place to invest. And indeed it is a repeat business and a single in that. Can not get any simpler than the weekly removal of dirt from someone's car when it is only going to get dirty again. Seems to be a bargain made in heaven and in fact half of what it was.
