    How these numbers are made

    • Every figure comes from service records Porsche owners logged on Elferlog for their own cars. This is what this group of owners paid — not a market average, and not a manufacturer estimate.
    • Only completed work with a recorded cost is counted. Planned work, AI suggestions and fuel fill-ups are excluded.
    • Owners log in their own currency. Amounts are converted to US dollars with a fixed reference rate table, so the numbers stay stable between visits rather than moving with the FX market.
    • Medians are used everywhere, not averages — one engine rebuild should not decide what an oil service costs.
    • A figure is only published when at least 5 records from at least 3 different cars support it. Anything thinner is shown as “not enough data yet”.
    • Categories are shown as a share of records that have a category set, not of every record.
    • No personal data, no individual car and no owner is identifiable from this page.
