02 Format Mix

Do they operate the same format of car wash?

Format Big Dan's Car Wash Sparkling Image Car Wash
Full Service 0.8% 9.8%
Detail Shop 0.8% 8.7%
Express Tunnel 3.2% 1.8%
Hand Wash 0.5% 2.7%
Self-Serve Bay 2.3% 0.3%

Format share is computed across customer review mentions, not over locations. A chain with mostly express-tunnel sites but heavy detail-shop talk in reviews will show both at non-trivial rates.

Both chains are predominantly Express Tunnel operators, so they compete head-on for the same customer occasion. The choice between them is largely about brand, price point, location convenience, and customer experience rather than format differentiation.
