Caveats

1. Source‑of‑Opinion Caveats

  • The Index reflects customer sentiment, not the views of Carblah.
  • Carblah does not alter, curate, or influence the underlying opinions.
  • Carblah does not verify the factual accuracy of individual customer comments.
  • Carblah does not endorse or criticise any dealership or OEM.
  • Carblah acts solely as a compiler and analyser of customer‑generated feedback.

2. Data Origin & Integrity Caveats (Carblah‑owned dataset)

  • The Index is based on customer reviews held within the Carblah dataset.
  • Reviews are verified and processed within the Carblah platform.
  • Automated filters reduce duplication, spam, and bot‑like activity, though no system is perfect.
  • Review volumes vary by dealership; lower‑volume dealerships may have wider confidence intervals.
  • Sentiment analysis may misinterpret sarcasm, humour, or ambiguous language.

3. Methodology Caveats

  • The methodology uses standardised, boilerplate sentiment‑analysis techniques.
  • Weightings and transformations are algorithmically derived, not manually chosen.
  • No dealership, OEM, or commercial partner has any influence over the methodology.
  • The methodology is designed to be transparent, replicable, and auditable.
  • Methodological refinements may be introduced as part of ongoing development.

4. Statistical Caveats

  • The dataset includes 200,000+ customer reviews, providing statistical significance.
  • Sentiment scores represent probabilistic estimates, not absolute truths.
  • Small differences between dealerships may not be statistically meaningful.
  • Confidence intervals vary by review volume and sentiment distribution.
  • Outliers may influence results despite filtering.
  • The Index is a comparative measure, not an absolute measure of dealership quality.

5. Temporal Caveats

  • The Index reflects sentiment at the time of measurement only.
  • Rankings may change as new customer feedback becomes available.
  • Certifications are valid for the stated period only (e.g., Apr 2026).
  • Year‑on‑year comparisons may be affected by changes in review volume or customer behaviour.
  • The Index is recalculated periodically and may be updated without notice.

6. Audit & Academic Caveats

  • The methodology is pending independent academic audit.
  • Carblah does not claim endorsement by any academic institution at this stage.
  • Rankings may be refined following academic review.
  • The Index is published in good faith with the intention of future academic validation.

7. Scope & Coverage Caveats

  • Only dealerships with sufficient customer feedback volume are included.
  • Some groups or OEMs may have incomplete coverage due to limited available data.
  • The Index focuses on retail automotive dealerships and service‑only sites; commercial vehicle operations, and excluded categories are not included.
  • New entrants may appear mid‑cycle as data becomes available.
  • Dealership mergers, closures, or rebrandings may affect continuity of results.

8. Platform‑Dependency Caveats

  • The Index depends on the availability of customer review data within the Carblah dataset.
  • Changes in data availability, volume, or structure may affect future calculations.
  • Carblah is not responsible for the accuracy or completeness of customer‑generated feedback.

9. Interpretation Caveats

  • The Index should not be used as the sole basis for commercial or operational decisions.
  • Sentiment does not necessarily reflect operational performance, compliance, or financial health.
  • High sentiment does not guarantee customer satisfaction in every case.
  • The Index is an indicator, not a certification of legal compliance or service quality.
  • Dealership performance should be interpreted in context, including local market conditions.

10. Badge‑Specific Caveats

  • Badges represent relative performance within the Index, not absolute quality.
  • Badges must display the year to avoid misrepresentation.
  • Badges may be withdrawn or updated if underlying data changes significantly.
  • Dealerships must not alter, restyle, or misrepresent badges beyond approved formats.
  • Badges do not imply endorsement by Carblah or any academic institution.

11. Legal & Liability Caveats

  • Carblah accepts no liability for business decisions made based on the Index.
  • Carblah is not responsible for inaccuracies in customer‑generated feedback.
  • Carblah does not guarantee the completeness or accuracy of the dataset.
  • Carblah reserves the right to correct errors, omissions, or anomalies.
  • Carblah may update or revise the Index without prior notice.
