A car purchase is an important decision and so people should take the time to find out if it is better for them to lease or to buy. Your priorities and lifestyle are the two contributing factors in this choice. What is right for one person can be the worst choice for someone else.
Leasing is a way to pay for the use of a car the belongs to someone else. Leasing can be troublesome as it is very hard to transfer or even get out of a lease. Typically, once in a lease, you stay in it for the term agreed upon. Financing on the other hand makes the car totally yours, no restrictions.
It really comes down to how much you want to spend and when you pay it. If you compare the same car, same price and same down payment, a lease will be about 30% to 60% less than a loan payment to buy. In the end, you decide if you want more car for less a month or you want the option to sell your car whenever you want. You cannot customize a leased car and mileage will be limited also but you have not worries about warranties or registration costs.
