OTHER cars start looking and feeling old after five years. But the 5-Series BMW? Not this one. The German marque has again breathed new life into its mid-size luxury sedan and the 530i Sport is a fine example. In appearance, accommodation, performance from the new-generation 3.0-litre engine and driving dynamics, this is a car for small families to revel in. Not all passengers will appreciate the sacrifice made in ride comfort. But the keen driver will.
