I bought my 04 with 135 on it and it just rolled over 190k, I have had the head gasket issue at 170k and when we had the motor opened it looked amazingly good inside, very clean, cylinders looked great, heads were clean, no gunk. Also replaced any gasket we came into contact with, bearings in all of the pulleys, water pump and one injector that looked suspicious but may have been fine. Just recently we have replaced the brakes with gen 5, one front wheel bearing and driver front axle shaft. Also recently replaced front and rear sway bar bushings and front end links. Ball joints appear to still be fine.
It helps that I could look up the POs service history on the Toyota website and my son is a mechanic. Other than the head gasket issue it has been a very reliable vehicle, I would not hesitate to drive it anywhere, any distance. I plan on driving this for a long time.
