This gets discussed every so often.
Leasing is good for some but in no way is it cheaper. Cars don't fall apart after 3 years
Well to be honest, it's just a question of what the comparison is. If you compare leasing to actually buying/financing and selling/trading in every 3 years, leasing is probably a fair amount cheaper, because it's a more efficient way of doing the same thing. But if you can hold on to that bought/financed car, maintain it well, and drive it till it dies (or at least a significant number of years, say 7-8) it's basically impossible to lease instead and come out on top after those 7-8+ years.
