Wish I had More.
 Overall a great car.  Smooth ride, quiet and comfortable.  The engine in the 525 seems underpowered for the vehicle size which causes the transmission to shift strangely in gears 1 and 2.  Very little road noise, great handling and gas mileage.  Contrary to many comments the iDrive is not that difficult to learn.
