I wouldn't want to own this car - or any of today's high tech, high performance cars - out of warranty. That being said, I generally (i) wait until the car has about 6 months left on the factory warranty before I buy the extended and (ii) only buy BMW's extended. First, you have the time value of money which is likely to cover any (or at least most) increase in purchase cost. Second, there is always the chance that a car is stolen or totaled in which case you lose the value completely. You might also tire of the car or need to sell it for some other reason. The extended warranty will add value, but not in the full amount you paid for it.
