I just bought 2011 X5M with extended warranty. I paid slightly over 3k for 5 year/100k miles.

Not many aftermarket warranty companies will sell you warranty for M cars (AMG are the same way). But I found that if you find a car you like from CarMax, you can get their 5 year/100k warranty (yes- you can take it to BMW dealership for all your service) for about 2k (most inexpensive deal and we know CarMax is not gonna go out of business anytime soon).

So make sure to check out X5Ms on CarMax as well.
