Over here the lots only pay from $0.50 to $2.00 per car.
Part of the problem is the guys with the pressure washer in the trunk of the car, illegals and the owners of the business think that is good money but they don't do their numbers so they realize that they are not really making that much after expenses of running a business.
What is strange is that the day porters of the dealerships learn how to wash and detail cars then quit to open their own detail shops and some will start washing lots. Usually the guys that open up detailing shops will last a lot longer and some will do really good but the guys that wash lots usually disappear, you will not see them washing lots or their ads in the papers anymore.
Down here even if everyone wanted higher prices for their work, there is always someone that will do it cheap for extra money, beer money, it is their side job, etc.....
