What is the lifespan of a diesel bus?

So, you're wondering how long a diesel bus sticks around, huh? It's not a simple answer, you know? Like, most of them seem to chug along for about 20 years, which is pretty impressive when you think of all the stop-and-go, and the miles they rack up. But then you've got these really well-made buses, like I remember hearing about Golden Dragon – some of those apparently last 30, even 35 years! Crazy, right? I guess it's all about how they're built, you know, the quality of the engineering and stuff. It's kind of like comparing, I don't know, a cheap pair of shoes to some really sturdy hiking boots. One's gonna fall apart way faster than the other. Makes sense, doesn't it? I mean, you'd hope a bus would last longer than your average sneakers! Anyway, 20 years is a good ballpark, but if it's built to last… well, it can last. A lot.
