Request for Startup: Subscription Car Wash a la WeWork

Here in Denver I subscribe to a monthly car wash membership for my black SUV which allows me to bring the car in as many days as I want for the same price. Since I have a black car I use this a lot, especially in the winter months when the car is constantly getting splashed with dirty slush. I rent my car out on Turo, so year round I use this service quite a bit (after each transaction) and also let my passengers know they are welcome to take the car in anytime they like. You’d be surprised by how many do! Denver people are the nicest.

I’m fascinated with subscription business models (I just got an unlimited monthly subscription for my eyelash extension fills!) and this one seems ripe for a WeWork-style startup to score real-estate and create a consistent U.S.-wide (or even global) car wash experience BRAND. They could buy up existing car washes. They could partner with them and provide McDonald’s-style “university” to help franchise owners maximize the value of their property with best practices. They could use collective bargaining to get better deals on equipment, supplies, etc.

Does this startup exist? Are you building it? How would you start?

Update: Thanks to Sachin Agarwal for pointing me to Spiffy, who recently raised $8 million in Series A financing
