Paper logs work — that's why they persist
A notebook in the glovebox is the oldest maintenance-tracking system there is, and it still works: paper vehicle log books remain bestsellers on Amazon, and enthusiast forums are full of owners running the same single sheet for a decade. The format above sticks to the columns that matter — date, odometer, service performed, parts or shop, and cost — because that's the complete grammar of a service record. Every warranty adjuster and used-car buyer reads it fluently.
Print a page per vehicle and keep it where the work happens: the glovebox or the garage wall. The discipline is the same as any log — write the entry down while you're still next to the car. An entry made "later" usually isn't.
Where paper (and spreadsheets) fall short
Paper has two honest failure modes. First, reminders: service is due by distance, but calendars — paper or digital — only speak in dates, so mileage-based intervals silently slip past. Second, permanence: a glovebox sheet doesn't survive a car sale, a coffee spill, or fifteen years reliably, and it can't hold receipt photos. Spreadsheets fix legibility and math, but keep the same blind spots — no odometer awareness, awkward at the gas pump, and no evidence trail attached.
If you keep records because they're worth money — and they are: a documented service history can add roughly 10–20% at resale, and dealers ask for exactly this documentation in warranty disputes — the log eventually wants to be somewhere durable, searchable, and dated beyond dispute.
The upgrade path (when you're ready)
The CSV template on this page is deliberately the same shape as Odobook's import format. Start on paper or in Sheets today; if the habit sticks, move the history into Odobook and keep going with reminders by date and mileage, fuel statistics, and receipt photos attached to entries — with everything stored on your device, exportable back to CSV for free, forever. No lock-in in either direction: the sheet upgrades to the app, and the app always exports back to the sheet.
