Reference Report — specimen
What one Reference Report contains
This is the shape of the €490 Reference Report, laid out exactly as a buyer reads it, with a specimen Reference in place of a real one. Nothing is withheld from a real report: every indicator arrives with its sample size, its confidence interval where one exists, and the date of its last observation.
A real report names the model. This one does not, because the numbers on this page are not measurements and we will not attach an invented figure to a manufacturer's product.

Table 1 — Indicators
Median resale price
€203
At month 36, against a launch price of €549.
n = 214, 95% CI ±2.4%
Depreciation curve
−63.0%
Total loss against launch price at month 36. Fitted M+1 to M+36.
n = 214, R² = 0.91
Monthly discount rate
−2.7%
Implied by the fitted curve, month over month, M+1 to M+36.
n = 214, 95% CI ±0.3
Days to sell
34 days
Median days between first observation and presumed sale.
n = 68, 95% CI ±5
Liquidity Index
62
How readily this Reference clears. Segment median is 50.
n = 68
Cannibalisation test
−7.4%
Price movement in the 90 days after the successor model was announced.
n = 96
This is a correlation, not a causal estimate.
Value Retention Ranking
57.0
Value retained at month 12, base 100. Price-segment median is 54.2.
n = 214, 95% CI ±1.8
Anomaly flag
2 clusters
Two price clusters in December 2025 the method cannot explain. Raised here rather than smoothed away.
n = 214
Flagged, not corrected. A real report links each flagged cluster to its observations.

Files
A real Reference Report arrives on screen and by email, as a PDF with the CSV of every observation behind it. The specimen CSV below has the columns a real one has, with 48 illustrative rows in place of 214 observations.
48 rows, 7 columns. Illustrative values, no observations. The file opens in your browser or spreadsheet.
What a real report changes
Two things, and only two: the Reference is named, and every figure is a measurement carrying the date it was last observed. The layout, the indicators, the sample sizes and the source register are exactly what you see here.
Coverage opens with one permitted source. Until a Reference reaches 30 observations there is no page for it and no estimate from us.
Tell us the Reference you want measured first and it goes to the front of coverage. This opens your mail client. There is no form on this page and no list to join.
