I jumped on one that fell in my lap while ordering my wife's X7. Salesman knew a client that had it on a lease that was ending, so it never hit the lot.
It's probably the last big M car with an 6MT, so I don't foresee selling it any time soon. It took me 2 years of looking for one and it's amazing to drive. If I can find another, I might just buy it and store it for later, like I do when I find a pair of shoes I like!
Put the service department through the ringer with warranty work. They probably put my name on a "do not sell a used car with a warranty" list.
