hi
that sounds about right. i have an 02 Sportcross (60k) and Glendale Lexus just charged me ~$400 for that job. normally i do my own maintenance on my cars but i just bought the Lexus used (50k) and this is my first Japanese car. the 60k wasn't cheap either ($900-1000) so i'll be picking up a set of the factory manuals soon...
