Hey Scotty from watching your videos I it makes me think of my cars. So let's start with the newest one:

2014 Toyota Sequoia 5.7 4x4, I bought it like 2 years ago and it had 87,000 miles. As soon as I had the chance I changed the fluids I did, aka engine oil, antifreeze, transmission fluid, transfer case fluid, and diff fluid. Also I changed the serpentine belt and all 8 spark plugs (the last two towards the firewall where a pain), air filter and caben filter. The milage now is like 97,000 not a lot of driving mostly family car. So on the sequoia should I need to look out for anything that is known to failure? 

2011 Toyota Tacoma Xrunner v6 manual, this one you will kinda hate because I did buy it from a salvage yard. The entire driver side was smashed and I fixed it to almost new condition had about 127,000 miles and now it's at 190,000. The engine runs great however the transmission is a different story. When the truck is cold it grinds into 3rd gear. When it worm up it seem like all the synchronizers are good until after driving for a while then when going from 1st to 2nd it grinds. Also when reving up in the high rpms it will grind from 2nd all the way to 6th. I think I need to rebuild it but that will be at a later time when I make it a weekend truck and not a daily. But for now is there anything else those trucks have problems with?

And last car is the 1999 Lexus Gs300 which we talked about and will ask more as I work on it.

Thank you,
