I've owned mine for about 7 years, and it now has nearly 240k kms on the original stock 3SGE motor.
Used mainly as a daily driver, but on occasions does get driven hard.
As for "Toyota reliability," apart from needing to get the aircond fixed, it has never missed a beat in the time I have owned it.
However I am very particular with maintainence. Anything showing the slightest sign of wear gets fixed straight away, and also a few things that aren't, just in case.
