I’ve been using the CarFAX Car Care app/website for a long time but I’m looking for something better.
It would be nice to have something I can enter my car make/model into and have it suggest maintenance but also keep track of repairs. I like uploading PDF scans of receipts too; one thing that always bothered me about Car Care is the horrible, weird compression it does on those files.
That’s my method as well. That and a folder to hold all the receipts. When I sell the car, I print out the spreadsheet and then trash the receipts.
