had a F01 730d for 75K miles ( truth been told, motorway miles)
Very low maintenance cost overall, no mechanical failure what so ever
Now the G11 740d xdrive, 10K MIles, no problem what so ever, first service after another 10K miles.
again, these are mostly motorway miles. So far so good, G11 is a big improvement over F01. Still interested in getting LS though
