To keep you all in the picture, i booked my car in to my mechanic to fix the timing belt but he could not get the belt from his supplier, so being a gold member i went to get my 5% off from lexus parts department. i told the person who served me the situation and asked to speak to a lexus mechanic for any suggestions of what might of caused it. the mechanic saw the photos of the belt and was so shocked it had gone that bad at such low miles, they picked the car up and are doing all the work for free :D :D :D it is a five year old car but he said that the belt is no where near the 100k change.
Lexus customer service scores 10/10 with me :D
