Fan belt - I guess they mean timing belt? That should only be done at 100k miles.
It states in the book DRIVE BELTS
Which when you speak to Lexus UK they state that this means the FAN Belt
Not the Timing belt/cam belt.
My 60000 on an IIS200 service quote was £671 at Lexus Bristol £300+ on top of the £671 if I wanted them to also do the cam belt.
I called Lexus uk to ask about the initail £671 and they said they would get Lexus Bristol to call me back to explain there pricing, which they had already done.
Anyway sure enough within 5 mins lexus bristol called me, I told them not to worry, they then said theyve managed to apply some discount and the price is now £491.
Sounds strange and unbelievable I know but that is fact, what lexus uk told them Ive no idea.
