KKE 318 : Automatic 3 - Brush Car Wash System

I am in a process of evaluating Car Wash Business. I do not have any experience about this business also. Would KKE 318 car wash equipment be ok for my initial investment. I may upgrade later on by installing KKE 300 at the same place?

Yes. You can install KKE 318 car wash initially and later have an additional bay with KKE 300 car wash equipment or install it at the same place as the layout, rail dimensions are same for KKE 318 and KKE 300.
Secondly KKE 318 is an entry level car wash equipment which helps to achieve the break even very quickly. So this would help you in your financial aspects too.
