I did some work on a really, REALLY abused example recently. One of the 'brochure delivery' hacks at my old man's business.
This thing is punished mercilessly by all manner of hopeless female pilots, touch parked, filled with hundreds of KG of shiny literature, and generally just flogged.
Currently has 460k on the odo and ticks along fine, blows no smoke, grinds no gears.
Only ever had regular servicing, one clutch (100k ago) a pair of cv's, and the usual wear items like pads and rotors.
All the girls whinge about it, saying it should be upgraded... Old man says "Fine... I'll replace it when the aircon dies"
Its a Corolla. The aircon will never die.
