leasing can work very well if you are able to play their rules, aka milage, maintance, milage, ect., as well as, physically place into savings or an investment, the difference that you would have paid for the car if you had traditionally bought it with a traditional loan (5 year) vs what you are paying with the lease. If you can not afford the vehicle's "payment" on a traditional loan, I would NEVER suggest leasing.
example.
65000 boxster, 5 year loan, @ 5% = $1,226.63
65000 Boxster, leased = approx. $800
You would take the spread ($426.63 per month) and put it in an investment/savings.
