I already have 4 cars though >.<


Buy or Lease?  If you want a long term commitment and reduced costs from over the length of ownership buying is always the way to go as long as you 1) don't buy a piece of shit, 2) actually do regularly scheduled maintenance.  Leasing is a more viable option if you want an unreliable or problematic car that includes free maintenance and will get another lease at end of term.  Fiscally speaking, you need to do a conversion between rates and cash factors and consider whether the dealership will try to screw you on the deposit or not.  Also modding.  As one who tears his cars apart, leasing isn't a real viability since it's not my car.  If I wanted a BMW, Caddy or Merc and never wanted to turn a wrench I'd consider leasing.  Leasing is decent future-proofing if you want to keep up w/ the Jones's and have the latest tech out there.  TPMS, FLIR, HD radio, Pre collision, Radar cruise, articulating projectors, etc, etc.  You also have to consider depreciation if you would consider a buyout of your lease.  Poor depreciation and residual value will wreck your lease if you might consider a buyout as a lease option.

Think of it as less an economic consideration and a lifestyle choice.  Leasing is much more about a lifestyle choice that may or may not have benefits based on your personal financial situation.
