Here is my responce to a post in the general discussion area.....
I changed my oil and cleaned the aftermarket filter, coolant flush, rotated the tires, insepcted the fluids and brakes.
So then I took the car to Lexus of Annapolis, told them what I had done myself, and they took it from there.
The total price was $200.......The orignal price quoted to me was $575 if they did the entire service.
So I paid $200 plus the price of the parts I bought.
