I like Audi's "I-Drive" interface better than BMW, and the Audi (at least the A8 that my friend has) you can disable Rain-Sense and have a true intermittent windshield wiper that the DRIVER actually controls. Also, the Audi (and I think M-B, but not sure) will stay in whatever drive mode (Sport) you put it in - you don't have to set it every time you get in the car.
