Francisco is spot on. Leasing is almost never better than purchasing. If you decide you don't like the car and want something else, you will have to find someone to take over the lease, which is more difficult than finding someone to buy the car you purchased. In addition to limiting how many miles you can put on the car, the dealers can ding you for "wear and tear" when you turn the car in.

I've written a post on this, comparing buying vs. leasing with hard numbers:
