Thank you everyone. It is a 3.0 tdi quattro black edition. So much smoother, quieter and obviously quicker than my previous 520d. And I would say the same compared to the one before that; a 530d. I'm a convert after only the test drive. The tech inside is amazing too. It has a few extras listed below. Can't wait to pick it up, and can't wait to pick your brains on things I need to know.
