User-Rated rankings combine verified-owner ratings across five categories — reliability, value, comfort, performance and ownership satisfaction — and require a minimum of 30 verified ratings before a model is ranked at all, to avoid small, unrepresentative samples skewing the list. Ratings are weighted by ownership length (a 3-year owner's reliability rating counts more than a 1-month owner's) and reviewed for suspicious patterns before being included.
At a glance
| Detail | Standard applied |
|---|---|
| Minimum ratings to rank | 30 verified ratings |
| Rating categories | Reliability, value, comfort, performance, satisfaction |
| Ownership-length weighting | Longer-owned ratings weighted higher on reliability |
| Fraud/spam screening | Automated pattern checks + manual review of flagged spikes |
| Refresh frequency | Rolling, recalculated monthly |
What counts as a "verified" owner rating
A verified rating requires confirmation that the rater actually owns or has owned the vehicle being rated — not just a general site account. This filters out ratings from people who've never driven the car, competitor brand-war voting, and simple spam. Unverified submissions can still be viewed for context on some pages but are excluded from the ranking calculation itself.
The five rating categories
- Reliability — how the vehicle has held up mechanically and electronically over the owner's actual time with it.
- Value — whether the owner feels the price paid matched what they got.
- Comfort — seating, ride quality, noise levels, day-to-day livability.
- Performance — how the vehicle drives relative to the owner's expectations for its class.
- Ownership satisfaction — an overall "would you buy this again" style measure.
Why ownership length changes how a rating counts
| Ownership length | Weight on reliability score |
|---|---|
| Under 6 months | Lowest weight — too early for reliability to show |
| 6 months - 2 years | Moderate weight |
| 2-5 years | High weight |
| 5+ years | Highest weight — most informative on long-term reliability |
Value, comfort and performance ratings are weighted more evenly across ownership length, since those impressions form relatively quickly, but reliability specifically is weighted toward longer-term owners because early-ownership reliability issues (or lack of them) aren't representative of how a car holds up over years.
How we screen for fake or manipulated ratings
- Automated checks flag unusual submission spikes (e.g., hundreds of 5-star ratings for one model in a single day).
- Verification requirements (proof of ownership signals) filter out non-owners at submission time.
- Manual review of flagged patterns before a suspicious batch is included or excluded.
- A minimum sample size (30 verified ratings) before any model appears in the published ranking, reducing the influence of a small, possibly coordinated group.
How the final ranking number is calculated
Each category score is averaged across all verified ratings for a model, with the ownership-length weighting applied to the reliability category specifically. The five category averages then combine into an overall score used for ranking. Models with fewer than 30 verified ratings are shown as "not yet ranked" rather than given a potentially unreliable score based on too few responses.
A handful of extremely positive or negative ratings posted in a short window is one of the clearest signs of a coordinated rating campaign — treat any user-rating system without a minimum sample size or fraud screening with caution.
