I don't think cars are a good example. Cars last much longer and with far fewer significant problems than they used to. A car made in the 1970s would maybe last 100,000 miles, if it didn't rust out first. And it would likely have one or more significant problems in that time (transmission failure, major engine problems, etc).
A new, mass-market quality (e.g. Honda) car made in the last decade will easily go several 100K miles if given basic care, and will probably not have any major problems or be showing much if any rust in that time.
Eh, when you consider the drive-train of your average 70s American car there's nothing preventing it from going 300k. The same small-block v8s and 3spd autos were used through the 90s with very good reliability. It's the little crap going wrong everywhere else that makes people upgrade.
