Looking to purchase a self serve with one express bay in Southern California. In the vicinity there is a competitor a few miles away doing express washes and opening up a few more locations; not within 2-3 miles of subject property. Would it be a better business strategy to keep, remodel and run this as is for a few years to see how the competition effects current cash flow before converting to full express? Need some advice from experienced owners who have both converted and owned self-serve. Maybe there is a population of people who still prefer having the option to go to self serve and that would differentiate the business for a while. Idea would be to convert in the long term..
