I would just like to say my IS200 T Reg is now on 105000 miles and is still running very sweet, Lexus in Warrington wanted £180 for the 100000 service and £336 for the Timing Belt, An hour before the service i read the service book and found out that all they really did for 180 notes is Change Brake Fluid, Change Diff Oil, Change Engine Oil and Filter and replace A/C Filter In Dash, It was at that point i cancelled my appointment and bought all service parts myself and did the full service at the Garage i used to work at which took about an hour in total, The garage next door is doing the Cam belt and all the other belts for 45 quid plus parts... It has not worried me that Lexus didn't service the car, I think the car lost alot of value the day it reached 100000 miles...
I guess the point to my little story is "If you are going to keep the car for Quite a Few Years it's not going to matter that much about sale value" After all look at the way New and Used cars are dropping in Price...
