I think, if Lexus was smart, they would purchase the high-mileage vehicles from their owners and tear them apart to determine what / why they lasted so long. Was it tighter design tolerances, driver habits, materials used, etc? But, on second thought, who would want to learn why things last longer or how to make them last longer when you are in the business of selling those very same things?

i get the self-congratulating here, but really a million mile car is hardly exclusive to lexus or toyota...
all kinds of brands do it.

At one time, decades ago, I had some truckers tell me that the average life of a big semi-freight truck is a million miles on the road, but that is with multiple engine/transmission overhauls and or replacements. Typically (at least from what they told me), when a semi's diesel engine is worn, they pull it every few hundred thousand miles, replace the internal moving parts as needed (bearings/valves/pistons, etc...), and simply re-use the block. The block itself often goes a million miles or more.

Remember, that was decades ago. Today's semi-diesel engines may be lasting longer. I can't say, because I myself don't have much experience with that type of vehicle, although my best friend in high school (who, like me, was a big fan of American full-sized luxury cars of that era) went on, after several local jobs, to become a long-distance truck driver.

It's all about the engine. The link below talks about the 4.7L engine that Toyota used in those years. Not the most efficient or powerful but design wise fantastic.

These engines do not have any design flaws, meaning lash, noise, wheezing cannot be found.

According to the Google machine, it's about right. Major companies tend to sell their trucks between 400-600k miles to smaller operators, who typically take them to about a million before retiring them. It's apparently extremely rare for an OTR diesel engine to remain in use past 1.5 million. It's possible, just not economically reasonable.
