Basically, everything you listed is routine maintenance and would have to be applied on any car.
Of course. That's why I'm wondering if he paid for it, did it himself, or managed to somehow avoid needing most of it.
I've never had a need for tire pressure sensors because I know how to use a $.99 air gauge or even my eyes.
Eh, now I think you're getting a bit into luddite territory. My 2000 model has tire pressure sensors. (Not very good ones, to be honest.) Very smooth car. I can have one tire at 20 PSI and the others at 30 and not notice - it rides the same. Looks the same, too, with a simple visual inspection. It's nice for the car to tell me, hey, yo shit is whack. I'd rather know I caught a nail when the tire is still holding air, not when it's nearly empty. I've never had to replace the sensors. Turning the alert off (after either fixing the tire, or more likely, checking that everything is completely okay and the sensor glitched a little due to just recently having mucked with wheels, or due to a small leak) is a press of a button.
With that said, I know a guy with a porsche who needed his TPMS sensors replaced - all four. Because the batteries were dead. Oh, and because the batteries can't be swapped. No, wait, it gets better. He got OEM replacements - $150 each. With labor, it came out to a thousand bucks. Granted, he tracks the car and probably would like accurate real-time reporting, but, come on, who the hell designs a $150 (x4) wearable part with no battery replacement possible?
every time I hop into one, it has a tire light on because "Those sensors are expensive! I'd rather just forget about the light."
Either that's a bit of an exaggeration or you drive with a lot of stupid people. Yeah, I've heard of people driving with the oil light on, too. Dumb ass thing to do unless the car's a complete beater.
