I created this excel spreadsheet myself with the primary aim to not be intimidating to potential buyers if the time ever came to sell. My aim was to minimise clutter while still providing comprehensive details on each service to instil confidence in the work completed. I added the main service items and anything that isn't changed regularly goes under miscellaneous. On top of this I also keep receipts and take pictures of me performing each service as well as one picture of the mileage.
