For one of the questions.. I actually ran into this dilemma myself when I purchased my 2018. I wanted to be able to make sure things were done properly and save money without it seeming like I didn’t properly maintenance my vehicle. I don’t really have a solid answer, but what I have been doing is logging all of my oil changes and tire rotations into carfax so if the next owner/buyer is looking for them they can find them. Carfax also gives you the option to add receipts, miles and data for each log so it’s more legit I guess. You log them as a DIY so you can see when you did it vs a shop.
