First 7 Series BMW following mostly Japanese luxury (Lexus, Infiniti) and also a Benz. This car is a lot of fun to drive and really couldn't be more comfortable. I have typically stayed away from European cars because based on my high mileage each year, I am always concerned about reliability. So far it has been problem free and more enjoyable than previous cars.
Bluetooth technology; sound system; driver's seat.
Not sure I am a fan of the keyless ignition but I understand how it would be an important feature for many drivers.
