During your test drive, listen closely for a rhythmic 'rattle' from the engine bay at startup or idle; this is a common area to investigate regarding the Alloytec timing chain tensioners.
Check the transmission health by feeling for any hesitation or 'flaring' between shifts, as these units can show signs of wear if the previous servicing history is unclear.
Operate the air conditioning through all modes; given the age, it is worth confirming the compressor engages smoothly and the cabin temperature adjusts without delay.

Check the engine oil level and clarity, as these engines appreciate fresh, high-quality oil to keep internal components happy.
Ensure the coolant looks clean and green or orange, rather than murky, to protect your radiator and heater core.
Take a peek at the service history booklet; consistency is often more important than the exact mileage between stamps.
Verify that the power steering fluid is at the correct level and doesn't exhibit a burnt smell.
Test all exterior lighting and ensure the instrument cluster illumination is fully functional for your night driving safety.
