I usually never leased for the reasons above. It just seemed like a bad thing. However, we did just lease the wifes car about a year ago. Here is why:

-She had a lemon of a Subaru (motor rebuilt at 20k miles and new short block recommended 10k miles later. Good Subaru 2.5i oil burning). Subaru wasn't making life easy and we wanted out of it. She had 4 years left on her loan. The lease is 3 years and will eat up her negative equity in the time. Wife like to swap cars (on top of getting bad cars) so she had some negative equity built up.

-This gives her 3 years to try the car. If she loves it, we'll buy it out. If it's a lemon, we give it back with a smile.

-The payment went down for her and she got a fully loaded Hyundai Santa fe. Buying limited the type of car due to trade in, negative equity, etc.

I'd still say that leasing is bad most of the time. It's good for eating up negative equity and avoiding negative equity if you swap cars a lot. Otherwise, I say buy.
