Good point about the air pressure. I check mine pretty often, any time the weather takes a change (in Oklahoma that's pretty often) and all 4 are usually about 3-4 lbs low. All 4 tires are always down the same amount, so I doubt it's a leaky sensor.
I'll probably change my air filter every 15K, and my Yaris didn't have a cabin filter installed, so I bought one from the dealer soon after I bought the car. Probably will change it every 15K also.
Even my friends new Xd didn't have a cabin filter already installed, crazy that Toyota doesn't install them at the factory.
