How do customers rate each chain on the 7 pillars?
Aspect scores aggregate WashIndex's LLM extractions across each chain's reviews. Each score is (positive − negative) / total mentions, ranging −1 to +1. Numbers above zero mean customers say more positive than negative things about the aspect; below zero means the reverse.
| Aspect | ModWash | Trademark Car Wash | Winner |
|---|---|---|---|
| Wash Quality | +0.75 | +0.80 | Trademark Car Wash |
| Staff & Customer Service | +0.94 | +0.94 | Trademark Car Wash |
| Wait Time | +0.64 | +0.77 | Trademark Car Wash |

Both chains see roughly 12.3% of membership-discussing reviews mention cancellation friction — close enough that neither has a clear operational edge here.
Do they operate the same format of car wash?
| Format | ModWash | Trademark Car Wash |
|---|---|---|
| Full Service | 3.6% | 1.8% |
| Hand Wash | 1.5% | 2.6% |
| Express Tunnel | 2.1% | 1.4% |
| Detail Shop | 0.4% | 1.4% |
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.
