My personal opinion - don't lease. There are only two reasons to lease:

1) You plan to sell inside of 2-3 years anyway, so this is a convenient way to get rid of the vehicle in a few years instead of going through the hassle of selling the vehicle.

Problem with that: The mfr's aren't stupid. They know what the vehicle will sell for, and you almost always get screwed on residual value. They charge you lots of fees for this "convenience" as well, and the interest rates are always artifically high compared to purcashes. PLUS - you still pay a portion of the sales tax to the state/county. Plus the fact that you are paying all that money and really don't own a thing. Might as well rent a car for a year, might be cheaper.

2) The payments are cheaper, but you still get a brand new vehicle.

Problem with that: If you can't afford something, wait until you can. You're left with nothing but an empty wallet at the end of a lease. Renting anything (electronics, cars, homes) is not an investment, it's throwing money out because you can't afford to buy it.
