It's been a while. I'm a reformed 'car guy' and in the past did plenty of mods to my vehicles. For a while there though jiffy lube and the like were so cheap I don't know how they made a profit aside from upselling suckers on overpriced 'dirty' air filters and so on.
However the area I live in now my wife took her vehicle to get the oil changed and they charged her $77! (oil, filter and synthetic oil) Never again!
Oil change reminder came on in my jeep and my son is in the 'can I help?' stage so I figured it was time for him to start with that. Changing oil wasn't hard before but holy crap it's now even easier! The filter just has a cover you screw off and pop a new one in (don't have to screw the filter itself out, drain it separately anymore, etc.) and they've redesigned the drain plugs so you can get them unscrewed all the way without oil leaking out.
Seriously easy and so fast compared to days of old. Fun for my son as well, he had a great time helping.
