Petrol
Check this by shifting the transmission through P, R, N, and D while stationary; ensure there is no hesitation or sharp 'clunk' when engaging gears, as the 5-speed auto can show wear after many kilometres.
While driving at 80km/h, listen closely for a rhythmic humming sound; this may indicate the rear wheel bearings, which are common wear items on XV30 chassis vehicles of this vintage.
Test this by turning the steering wheel lock-to-lock while the car is idling; listen for any whining from the power steering pump, as high-mileage examples can sometimes develop minor leaks or pump fatigue.
Inspect this by checking the dashboard for sticky textures or melting spots; the 'soft-touch' plastics in this generation were prone to breaking down under the harsh New Zealand UV rays.
Usually marks the point where suspension bushings and struts may start to feel less firm, potentially requiring a refresh for that Lexus-smooth ride.

The stage where you might notice minor oil seepage from the valve covers, a common aspect of high-mileage V6 engines.
Verify the timing belt replacement interval has been strictly followed, as this is the most critical item for the 3MZ-FE V6 engine.
Check that the transmission fluid is a healthy red or light brown color; a burnt smell can be a sign that it may require a flush soon.
Ensure the air conditioning system is blowing ice-cold, as these units can occasionally develop minor coolant leaks in the hoses over time.
Confirm the power windows operate smoothly, as the regulator motors can become sluggish after many years of use.
Look for a comprehensive service history, as these engines thrive on regular high-quality synthetic oil changes.
Estimated repair costs if issues arise
Since this is an interference engine, it's wise to budget for this if the service history is missing, as it ensures long-term engine reliability.
If the car feels a bit 'floaty' on the motorway, you might eventually need to budget for new shocks or bushings to restore that signature Lexus comfort.
Depending on the car's history, you might eventually need to budget for a pump reseal or replacement if you notice persistent fluid dampness.
