Transparency How we rank
How we rank
detailers
Every detailer is scored by TopScore — a single 0–100 number that answers one question: how confident can a customer be that this is a genuinely top detailer?
What goes into TopScore
| Rating quality · 70% | The detailer's average customer rating, credibility-adjusted so a 5.0 from 8 reviews doesn't outrank a 4.9 from 400. We use Bayesian shrinkage toward the market average until a business has proven itself across many reviews. |
|---|---|
| Review volume · 22% | How many customers have weighed in, on a diminishing-returns scale. More verified experiences mean more confidence. |
| Service breadth · 8% | Whether the shop offers a full range of detailing services — ceramic coating, paint correction, interior and exterior, and more. |
Our principles
- No pay-to-play. Placement cannot be bought. Claimed listings add photos and details, but never move up the ranking.
- Grounded in real reviews. Summaries are synthesized from genuine customer reviews. We never invent prices, quotes, or criticisms.
- Curated, not exhaustive. We only rank detailers with enough verified review history to assess fairly. Thin or unproven listings are excluded.
- Transparent. The factors above are the whole formula — no hidden inputs.
