> Some people want a new car all the time. Leasing is not a bad way to do that.
True.
But does that make any economic sense? If you're so rich that it doesn't matter, sure why not.
But for most people leasing is a terrible economic decision. If money matters, never lease. If your wealth is past the point where money matters, go for it.
> As someone who drives a ten-year-old car that probably has several good years left
I'd say several decades at least. My new car is 13 years old, which I consider barely broken in.
Second oldest is 22 years old, doing great. My other cars are much older, in their third and fourth decades.
Barring a crash, older cars can go on for a very long time. Newer cars built these days have a very limited lifetime ahead of them, as the electronics will be unrepairable in short order.
