Findings · one number, one date
Automotive research
Research is the short form: a single number one of the car sites computed, the day it was read, and a link to the page that shows the working. Reports are the long form, refreshed from the same registries by scripts in the open, and they sit below the findings. This page carries the automotive work only.
One number, one date

33rd percentile
Read against 11,779 live German listings, the typical carpriceindex price sits at the 33rd percentile of what dealers are asking. None of its 201 prices moved in the 1 September 2026 re-check, and the note says so instead of inventing movement.
122 of 201 up
Across the 201 cars in carpriceindex's registry, 122 carry a rising 12-month trend estimate, 74 a falling one and 5 a flat one; the European mean is +0.7%. Modern classics lead at +3.0% with 43 of 48 up; saloons and estates trail at −1.9%.
65 platforms
Sixty-five real platforms carry stock figures whose source is named on the platform page, so a build is checked against the car it actually starts from. Each check returns a 0 to 100 build score, the weak link, severity-ranked risks and an ordered roadmap to the power goal.
7 of 26
Dual-duty is the largest category in brakepadfinder's registry, 7 of its 26 pad lines, with an average stated maximum temperature of 690°C and every line street-legal. Only 5 of the 26 lines are flagged EV-ready.
€5.20 to €47.79
Across the 15 European circuits in the index, one track-day lap runs from €5.20 at Brands Hatch Indy to €47.79 on the Nordschleife: more than nine times the price for the same hour of driving. Twenty-eight circuits are priced in all, each on typical track-day pace and a regional budget.
€362 to €1,520
One European car track day on lapcost's three spending profiles: €362.03 budget, €603.63 typical, €1,519.82 serious, computed from the model's own defaults and rule. Entry is 31% of the typical day; tyres are the largest line after it.

The long form
A report is listed here only if it is refreshed from a registry by a script in the hub repository, or carries its edition date and a pointer to the live number. The edition is on every card.
