Lots of factors to consider, and only you will know if it's the right decision for you.... but I had a friend who's husband was a car salesman - his words on the topic were "the car company wouldn't be doing it if they didn't make money on it"
There are a lot of terms and conditions, and if you drive a lot of miles/kilometers, it can be very expensive at end of lease. Of course, if you are able to write the expense off on a business basis that makes the decision much different.
