I have a 2RZ-FE (2.4 I4) Tacoma (the vintage where half were recalled due to rusty frames) with 390k and 3UZ-FE (4.3 V8) LS430 with 300k, both requiring just normal maintenance. If you change the oil, many Toyotas will just keep going. A large portion of car owners simply neglect their vehicles, though. I've always read that keeping a car on the road is a net win for the environment versus creating a new one, as long as it isn't some unreliable gas guzzler. That isn't to say that Toyota doesn't have bad cars, like the 2nd gen Scion XBs that had bad rings and would eat oil, or even LS460s with their control arm bushings being a $15k repair. Their modern quality probably isn't as high as it was in the 90's or early 2000's, as their focus has been on bigger vehicles for us fat Americans instead of better quality.
