I’ve been looking and haven’t found many. I’m not talking about big-rigs or any diesel. But the average car/truck people use as a daily driver. I’ve only found a handful. And of those how many are on the original engine?
We tend to keep our vehicles a very long time, but even a Million miles is pushing it - even for a well maintained reliable vehicle. And there are people here who’ve kept vehicles longer, but no one as reached 1 million miles yet (at least I don’t ever remember anyone claiming that). Most vehicles will probably reach end of life long before 1 million miles due to other factors (rust, transmission, suspension…etc…etc.
It seems so rare that when people do it…good things can happen.
The second part of this…WHY? Most people get rid of their vehicles long before the vehicle is dead. Either they don’t want to deal with repairs, or they get bored.
