Check the transmission shift quality by gently accelerating from a stop; in vehicles of this age, it is worth observing if the transition between gears feels smooth or if there is a noticeable hesitation, as the 4-speed automatic units may show their years.
While driving, pay attention to the dashboard for any flickering or dead pixels in the digital odometer display, as these units can sometimes become temperamental as they age.
Inspect the underside of the engine block for signs of oil dampness, specifically around the rear main seal, as it is helpful to note that minor seepage can be a common feature of the 1MZ-FE engine as the gaskets settle over time.
Test the climate control system by cycling through the heater and air conditioning modes, as the internal blend door actuators can occasionally become sluggish or noisy in older RX300s.

Often the time to evaluate the condition of the suspension bushings and struts to maintain that signature Lexus comfort.
Typically a point where the condition of the CV joints and alternator should be reviewed as part of regular long-term care.
Verify that the timing belt has been replaced every 100,000km, as this is a vital service item for the 1MZ-FE engine.
Check that the transmission fluid is clean and reddish in color, as clean fluid is helpful for long-term gearbox health.
Confirm the presence of a consistent service history, ideally demonstrating regular oil and filter changes.
Inspect the condition of all four tires to ensure even wear patterns, suggesting the wheel alignment has been kept in check.
Check that all interior electronics, including the power seats and windows, operate smoothly without binding.
Estimated repair costs if issues arise
Because this engine relies on a timing belt, it is wise to ensure it has been serviced. If it is nearing the interval, you might eventually need to budget for a complete timing kit replacement to ensure ongoing reliability.
To maintain the refined ride quality Lexus is known for, you might find that the struts and rubber bushings need replacement as they naturally reach the end of their service life.
It is quite common for the valve cover gaskets to become brittle over time. If you notice a faint smell of burning oil, it is a sign that you might want to budget for a resealing job.
