My 2006 750 li has only 60,000 miles on it. On vacation last month 800 miles from home my transmission failed. There was no warning or previous signs of a problem. The nearest BMW dealer said the only option was to replace it, it could not be repaired. Seemed strange that a failure should occur with such low mileage. $10,000 later I was on my way home. I called BMW NA customer service and got absolutely nowhere. This was called a"random failure" and offerd no help. Needless to say given this kind of a response my BMW buying days are over
