How it works
At a car wash, the price list is always two-dimensional: service type by vehicle class. Clients can't be bothered to decode that table, so they either call or go to someone easier to understand. The quiz works through the table for them: wash type, vehicle class, add-on services, and at the end the price of their package.
The add-ons in the template (engine wash, rust protection, tough dirt removal, A/C cleaning) are exactly what brings most of the margin, and what usually gets asked about at the last minute at the wash. In the quiz, the client sees them calmly and checks them on their own, without pressure from staff.
The last question is the location choice. The addresses in the template are examples, replace them with yours. For a chain, this also works as routing: the request goes straight to the right location. It's also worth adding a time slot choice: on weekends, the line is the main reason a client turns around, and booking a specific time solves that better than any discount.
