No road tax for this engine to be paid / low insurance. 2) Rear abs sensors, glow plugs, ac condenser - nothing major. 3) I service it every year (7-10k miles) and it works a treat, I use Castrol 5-30. 4) Got remapped. 5) At 155k nothing done with the chain. To be honest the engine and gearbox (manual), seem solid.
