Thank you guys. This is so helpful in making my decision.Thanks for all the tips. This is going to be my first BMW and I am looking forward to it. Another question if I may... To protect the interior leather, I should consider buying the leather protection service plan which cost around $500-$600. This way, my daughter's car seat will not damage the leather too much. Has anybody purshase that service? if so was it useful? According to a friend, the product that MBW uses is called SIMONIZ System 5. Thanks
