Do they operate the same format of car wash?
| Format | Crew Carwash | Jax Kar Wash |
|---|---|---|
| Express Tunnel | 10.8% | 9.9% |

| Hand Wash | 1.3% | 1.8% |

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.
