Yep, mine has 105K and it's fine. I have spoken with a cousin who is a mechanic and he said it should be good for at least 120K. I plan to change mine around 120K-130K. I change it around 100K in other cars before and the belt always still looks pretty new... so I'm not worrying... I know if you really want to push it, it's good for 150K or more.I changed mine at 90, but i am overly cautious. I would NOT do it earlier. If Lexus said 90, that is definitely conservative and earlier would be unecessary.
