I have 04 RX330 bought in Sep/2003. Currently 67,000 miles with not much driving. Did oil changes regularly at Jiffy Lube with 5 to 6,000 miles interval. So far no major problem for 9 years excepts tire replacement. As the car ages, I am concerned about maintenance. What should I do tune-up or something else? Should I go to dealer to do it? Any comments is appreciated. Stevehl.
