I did buy the extended warranty. My previous car was a Lexus LS460, which is supposed to be one of the most reliable cars, but I spent enough out of pocket on it to have paid for the cost of my BMW warranty.

I got 5 years 100,000 miles for about $4,100.

For the prepaid maintenance, it is indeed a math problem. Over a 100,000 mile period, you will likely save some money. However, over any given interval, you may not. The first three years, if you need brakes, you save a lot of money, but if you don't you need to sign up for the next interval. You must purchase the first 3 years to be eligible to purchase additional years, but you can add on anytime. You can see the cost at the MyBMW site, and the cost should not go up.

My concern is that normally I put on 20,000 miles a year. With the shelter on place likely to be with us periodically over the next 2-3 years, I may not get close to that, so the money may be wasted.
