I imported an Alfa 159 2.4 a while back and there was spotty service history, so it needed everything; a timing and aux belt replacement, full service, oil cooler kit €380 +vat + labour, and I opted for the Autolusso replacement intake manifold with swirl flaps welded up (€240 + labour + vat) while it was apart.
