Is It Expensive to Maintain?
No. Parts are widely available and cheap because the Passo/Boon shares components with other Toyota and Daihatsu small cars. Service networks are broad, and mechanics know the car.
Its small naturally aspirated petrol engine is mechanically less complicated than a modern turbocharged powertrain. However, cheap to maintain does not mean forgiving of neglect. A Passo/Boon with an incomplete service history and a tired CVT can become expensive quickly.
