Front calipers and pads replaced sometime in 2015 around 46000 miles.
House and car battery were replaced in June 2015 with AGM batteries.
Oil changes at least once yearly since 1994 including years with very little activity. I usually ran around 5k mile intervals on the oil, so after each big trip too if there was more than one long trip in a year.
Let me know if you would like more history going further back or if there is anything specific you are curious about and I'll dig through the maintenance history.
