a new car every 60 months, vs. say buying an older one. I don't know how that is apples/orange?
One could argue that I enjoy "shelling a ton of money" to buy luxury off-road SUVs, V8s to boot, and commute 60 miles per day to work when gas is $3.00/gallon when I could easily purchase an old Honda Civic beater for $1500 and save money at 35mpg.
And that would be a true statement. For me, having the off-road vehicle (which I use) is worth "shelling a ton of money for". I've run the numbers and the maintenance/insurance costs, plus accident risk (wildlife) in my area aren't worth it to me to get a smaller commuter. So I pay a premium.
Same with people who lease. They've run the numbers and they are willing to have that monthly payment for a new car. And in some cases, they come out pretty good for 60 months. But in the meantime you are still paying that $$.
