What he has to show for it at the end of the lease is $200 to $300 more per month in his pocket (or invested) for each month that he leased instead of financing for 48 to 60 months. Also, he may have some tax advantages if it is a business lease. And let's not forget the convenience and ease of turning in the car at the end of the lease and leasing a new one or just walking away without the hassle of trying to sell the car to a private buyer or trading it in on another car.
In the last 20 years I have leased or purchased two Porsche 928s, two Porsche 911 Carreras, one BMW 328i, and have a 330i on order. In my case, when all factors were considered, it sometimes made very good sense to lease instead of buy.
So, depending on personal circumstances, the words "lease" and "deal" are perfectly acceptable in the same sentence.
RChoudry, my order went in on April 9th and is scheduled for May 10th production, with delivery in late June. My dealer has said he will honor the agreed upon lease numbers until I take delivery of the car, even if it is beyond the 60 days. He has done this in the past for me so I have no reason not to believe him. If the money factor on the leases through BMWFS goes down before delivery he will refile the paper work and I will get the lower rate. Not sure if this is typical with all dealers but I have had nothing but good experiences with this one.
