2004 Lexus RX 330 - maintenance to prolong life

I have a 2004 Lexus RX 330 with around 220,000 miles. I’m wondering what maintenance I should have done to keep it going as long as possible. Thanks

Do the same things that got you to 220,000 miles. Unless you just bought this car… you don’t say.

What about that timing belt . . . ?!

I believe the replacement interval is 9yrs/105k, whichever comes first

Have you ever replaced the spark plugs?

How often have you serviced the automatic transmission fluid and filter?
