A dealer wash and a public retail wash can share equipment but have different service, access and accounting needs. Define capacity, responsibilities and transfer rights before projecting a hybrid business.

Define which customers the wash serves
Separate dealer inventory preparation, customer service washes, retail customers and paid memberships. Document whether dealer volume is paid under an enforceable agreement or is an internal service allocation. An internal charge is not automatically third-party recurring revenue.
Test when dealer demand overlaps with public queues. Reserved capacity, staff supervision and vehicles with unusual dimensions can affect retail throughput. A capacity plan should reflect actual peak periods.
Keep the operating records distinct
Track wash costs, staff hours, water/chemical use, payment collections and customer claims independently where feasible. Shared utilities and payroll need a consistent allocation that the buyer can understand.
Review customer promises and any free-wash entitlements attached to vehicle sales. Obligations that continue after a transfer can consume capacity even if the wash receives no additional payment. Identify who bears that cost.
Establish site and contract rights
Verify separate customer access, stacking, exits, parking, insurance and permitted public operation. Ask counsel whether dealer and wash entities have clear leases, service agreements and assignment rights.
A proposed wash carve-out needs more than a list of machines. Confirm rights to the building, utilities, signage, payment systems and customer relationships. An acquisition should identify how operations continue if the dealer relationship changes.
Model the opportunity as a specific project
Use written construction and equipment estimates, a capacity study and supportable demand assumptions. Present dealer commitments separately from speculative public sales. This guide describes questions to resolve, not a documented Illinois profit model.
