Just had my 15,000 service on my LS430.
Paid $170 for the service and in addition I changed the engine air cleaner for $30 and the cabin air filter for $76.
They also charged me (w/o asking) for new wiper inserts at $8 each and $2.50 for windshield fluid, although I just filled it myself the other day!
Seems very high and very aggressive.
