I have 5 dealership accounts and I charge 100.00 minimun for a dealer less than 50 cars! I also have 2 dealers with about 200 cars and I get 2.00 per car 2.50 per truck/van and have one helper I pay 10.00 an hour. All that I do is a Hot water rinse and you have to have quality chammy's to dry with. And be sure to rinse the chammy's every 3 or 4 cars to get a non streak finish. It is labor intensive because of all the drying but hey money is money and you can never make up for a lost buck!! Also remember that if they use a local car wash they will be paying for a driver,gas, and a minimum of 4 to 5.00 a car. Don't kill the industry at 1.00 a car!!
