I used to change the oil in my vehicles myself back when I was younger. It's gotten so it isn't as cost effective now, plus I am too old to be crawling around on the garage floor. I could still do it if I wanted to, that's what's important. My wife prefers to have a hands off approach with our finances, but I have good notes so if something happened to me she could still pay the bills.
It's pretty difficult to service new vehicles these days and I don't do it. Back in the day I did my own maintenance generally although I'm certainly not mechanic; the basics were within my scope.
That's very true. Most everything is done through the computer now and you need special equipment. I still repack the bearings on my trailer by hand every year. It doesn't take me too long and it helps me feel like I still deserve my man card. Plus it gives me peace of mind hauling that beast down the expressway!
Yep, that makes sense. I do my camper trailer annually as well, a maintenance plan, to prevent (minimise) incidents.
