A little surprised at some of these responses from here, since the response to this frequent topic on other ToyoLex boards always seems to be "why would you risk it". Yes, on my 2000 the PO had not had it done at 150k despite being religious with everything else, so I went ahead and did it (and then hated the transmission so much I traded it in right after, go figure) and the belt did show minor cracking/fraying. But in other Toyota/Lexus timing belt threads I was made to understand that a visual check of the belt means little as it's typically the WP itself or timing belt *tensioner pulley* that fail and throw the whole works to a grind. The time interval is 9 years, but I haven't ever actually heard of a toyota belt snapping due to age. Again, supporting parts, not the belt.
Now, if it's true that the 2UZ-FE is non-interference, then who cares who really. But to me, the "safe" region is 120-130k. At 107 I'd concern myself more with ensuring that all the driveline parts had had their lube services (diffs, trans, TC etc). These, and even the hydraulic fluid for the suspension were all done at either 60 or 90k on the 2003 I picked up last week for resale which along with being a 1 owner Texas truck went a long way to why I snagged it.
