Get the extended powertrain warranty but it's not worth your money in getting the extended "maintenance" warranty. Just save your money and find an indy shop that can get your car ready in a timely manner. It's not like it takes days to do an oil change or replace the brakes. I never cared for the loaners that the stealerships offer because they always gave me stripped-down 320i/328i plus I'd always have to plan a month ahead to even get one.
