Build it right: one row per service, one sheet per car

Use the eight columns above, one row per service, newest at the top, and freeze the header row. Give each vehicle its own sheet — mixing cars in one table is the most common reason spreadsheet logs get abandoned. A dropdown (data validation) for the work-performed column keeps 'oil change' from becoming five different spellings you can no longer filter.

Make the next-due column a formula: odometer at service plus the interval. That single formula is what turns the sheet from an archive into a plan, because sorting by next due shows you what the car needs before it needs it.

Where every template eventually breaks

The data model is not the problem — the workflow is. Receipts live in a camera roll or a shoebox, and linking a photo to a row means manual file management nobody sustains. Entering a record from the driveway on a phone means pinch-zooming a grid. And a spreadsheet cannot notify you of anything: the next-due formula only works if you remember to open the file.

The last gap appears at sale time: handing a buyer your raw spreadsheet means exporting, cleaning out personal information, and hoping the formatting survives. Evidence — the receipts — still has to travel separately.

Spreadsheet vs app, side by side

Neither tool wins every row. If you enjoy maintaining the sheet and have one car, a spreadsheet is a perfectly good log. The app case is built on the rows a spreadsheet cannot fix: receipts attached to entries, reminders that find you, and a shareable history — see the GR86 example linked below for what a shared record page looks like to a buyer.

Migrating without retyping years of data

Do not copy the whole sheet over. Start logging new services in the app from today, keep the spreadsheet as a read-only archive, and migrate only the records that matter at resale: major repairs, timing belt, and the most recent service of each type with its mileage. That is usually ten entries, not two hundred.

Whichever direction you choose, keep the eight columns intact. A history that records what was done, at what mileage, and when it is due again stays useful no matter which tool holds it.
