During your walkaround, press your fingers against the dashboard and door card surfaces to check for any stickiness or 'melting' texture common in early 2nd Gen models due to heat exposure.
While starting the car from stone-cold, listen intently for a brief rattling or 'grinding' noise from the engine bay which could suggest the VVTi gears may eventually require attention.
During the test drive, find a smooth road and pay attention to any wandering or vibrations through the steering wheel, as the front lower control arm bushings can show signs of wear in cars of this age.
While idling after the car is warm, check the tachometer for any fluctuations or a rough 'hunting' idle, which might indicate that a future intake carbon cleaning would be beneficial for the 2GR-FSE engine.
Major service interval including replacement of long-life spark plugs and a thorough inspection of the cooling system.
Ideal time to consider replacing the serpentine drive belt and inspecting the water pump for any signs of weeping.
Consider a comprehensive suspension refresh, including dampers and rubber bushings, to maintain the original Lexus ride quality.
A milestone to evaluate the health of the alternator and starter motor, which are common high-wear electrical components at this age.
Verify the use of high-quality 5W-30 full synthetic oil every 10,000km to protect the complex timing chain assembly.
Check that the car has been consistently run on 95 or 98 Octane fuel to satisfy the requirements of the D-4S dual-injection system.
Inspect the condition of the automatic transmission fluid; while 'sealed', many owners suggest a drain and fill for longevity.
Test the operation of all interior electronics, including the motorized steering column and seat heaters/coolers.
Examine the radiator end tanks for any pink crusting, which is a common indicator of a small coolant weep in Toyota/Lexus units.
Estimated repair costs if issues arise
In cars of this age, the water pump can eventually develop leaks. Replacing it typically involves a fair amount of labor in the engine bay.
If the steering feels less precise than expected, you might eventually need to budget for polyurethane or heavy-duty rubber bushings to restore handling.
Depending on the car's history, this is a more involved job than a standard car because the intake plenum often needs to be removed to access all plugs.
It is common to consider budgeting for a new alternator if you notice flickering lights or weak starts, as these units work hard in the IS350.
