I had mine done today for my 2001 IS300. Bill was $1582.73. I can tell a major difference in acceleration. It is not sluggish anymore. Rides like when I first bought it. I'm broke now. :o
I had a 60,000 mile service did on my 2001 IS300 today. Man it was $1582.73. Woooooooo, they said it will not be another major service until 120,000 miles. It rides much better now, i guess I can't complain now, eventhough I'm broke.
