I am sure you would get a better response with more details about the current site. What kind of wash do you have a self serve, full service, IBA, express. How old is equipment? Whats manufacture of the equipment? Are you original owner or a newbie in the industry that needs help. What state? Existing carwash equipment is so broad in this industry. Kinda like walking into a steakhouse and saying I want a steak, then the waitress responds what kind ribeye, fillet, NY strip,wagyu then they ask how would you like it cooked well done, medium well, medium rare, rare. You get the point on the form the more specific you are the more help you will get. Good luck
