I'm not sure exactly which autobox the 220i AT has. My old 225xe had the torque-converter 6-speed box which was excellent: very smooth and quick to respond to throttle input without getting mixed up. In Sport mode, the car is very lively indeed.

BMW's servicing costs are similar across its range of cars: it's 'condition-based' in which the car tells you when it needs servicing (no more than 20 months or 18,000 miles between services). The first service is a 'minor,' costing about £275, the second is a 'major,' costing about £360 or so.
