Yes i exactly do the same. Take my 2016 corolla to Toyota Motors and watch how they do the service, ask questions and do basic stuff my self like clean air filter, clean ac filter, do a brake service.
Did the same on my previous 2010 corolla and still learning stuff for my 2014 JDM wagon r
I also thought of making these types of video and starting a channel but ended up becoming a writer for Pakwheels so i have very little time to make videos and run a YouTube channel side by side
