Unless you go for a car that doesn't depreciate as much, or you get a good guaranteed minimum value at the end of the term, you will still pay for what you've used.
The other complication with leases on new cars, is you really need gap insurance to cover the finance. As soon as you drive off the forecourt it loses a fortune and unless you have the cash somewhere, if someone hits you, you are still liable to pay the finance. And since second hand cars are worth pence, you'd be up a creak.
If you want a good deal, I would suggest getting a secured loan on the car and buy a second hand one. I can put you in touch with someone to help you out if it helps. Especially if you fancy a used XC90.....
