I disagree. Eventually, plastic disintegrates from sunlight, wiring becomes brittle, connections corrode, and you start having horrible malfunctions with todays computerized crap everywhere. If you are an absolute perfectionist with every maintenance detail on your vehicle, you will end up with a rusted out short circuited piece of junk with a perfect drive train. What good is that?

Then, and only then, it will last forever
