No doubt. But I suspect you dont get too mnay bus owner coming into you and telling you what's wrong with their bus, becasue they "googled" it. And their mate, who has been driving buses since Easter, says that it's a definate warranty....
Buses, not so much - Trucks,
every-fuckin'-day.
"I need a new light control module because I've got a headlight out"
"Have you checked the headlight globes?"
"No, it won't be that. My mate had a headlight out the other day and he replaced the LCM and it fixed it."
"Are you sure it's not just a globe?"
"I know what I need, I just told you my friend has the same thing."
"I can sell you an LCM, but they're ~$1000, and can't be returned if they've been fitted."
"Just get it."
2 hours later:
"Hi, I want to return this LCM, it didn't fix my headlight."
"How do you know it didn't fix the problem?"
"I fitted it and the headlight's still out. That's why I want to return it. It was just a headlight globe blown."
"Unfortunately, as we discussed earlier - I cannot take this back."
"Why not?"
