How is your online game? Do you have a website, location claimed on Google Business listings and Maps, optimized for search terms like "car wash near me", mobile optimized your website, etc? I bought a car wash last year that had no online presence. I spent some time stepping up that part of the business. We're probably going to see an increase in revenue of 15-20% YoY at the one year mark. I can't say this is all due to the online work but it's definitely helped.
