I take my RX300 down the street to the Speedy Lube every 3,000 miles and they charge me $17 to change my oil. I take it to Toyota's express service every 15,000 mi. to change the transmission fluid. Costs $40. I change my air filter myself. Why would anyone take their car to a Lexus dealership for scheduled maintainance or any repairs other than warranty issues???? I'm amazed at how many people are throwing their money away!!!
