We all know that the 98-05 GS430/400 (same for 300) are interference engines and therefore if the timing belt snaps, the piston and valves can smack into each other and lead to internal engine damage. As a result, Lexus recommends replacement of the timing belt every 90K miles.
I'm curious if anyone here has ever had a timing belt actually snap? I hear that the OEM belts are Kevlar coated and extremely strong. As a result, I have never actually heard of one snapping on these cars. Most people who do replace them usually report that their original timing belt was in great shape with no sign of wear. I've even heard of guys going well over 200K miles with their original timing belts.
Does anyone have pics of their belt (and if so, at what mileage did you remove it)?

I replaced mine about 3k miles ago. The last belt maybe had 60k or 180k( last owner did not have proof of t/b replacement, just a sticker staying it was changed) looked fine but I changed it just to be safe. Job takes an afternoon and kits are about $350 including waterpump on rock auto.
I have a good friend of mine with a 99 GS4 - he bought it from a shady car curbing dude and I TOLD him to change the timing belt ASAP - well fast forward 6 mod and his car had been in and out of my shop for many little things - he forgot the timing belt.
So, one day at 180K kms, he decided to have us do the belt - you would NOT believe me but my partner went to pick up the car and on the WAY to the shop the belt BROKE.
