Iโm sure Iโve seen some software out there but I donโt remember the details. You could likely find it with an internet search. I use both Word and Excel to record my vehicle maintenance. Word is narrative style because I can record info that would be awkward to do on Excel, like issues that didnโt result in repairs or comments the mechanic made about the condition of systems. I find that handy because I keep vehicles much longer than memory would serve me. My newest vehicle is 10 years old and the oldest is 40 years old. Excel works good for concise details like what system was repaired, who did it, costs, when routine maintenance is due, etc.
If you have some familiarity with computers you can easily make up a log yourself. If not, Iโd do a net search for it. Thereโs also โfreewareโ out there that might have something along that line.
