Thanks for the very detailed thoughts, our other car is a 57 plate Golf TDI GT Sport and that too suffers from intermittant rattles (waiting for its 2nd trip to the dealer). I do not think this problem is a Lexus only problem.

Mine is an early model, it still rattles and squeaks intermittently and the dealer has been unable to fix it totally, though in the last year it hasn't been in (I don't want them to take anything else apart).
I seriously have been bitten by this badly, right from ordering the car and asking for production line verifiction that rattles would be fixed, to now - 2 years down the road. And it still rattles now and then...sometimes quite badly!
Having test driven several Courtesy's, including 250's, only one was rattle free. That is honest! Maybe I was unlucky, but I would recommend that you buy the newest you can afford - plain and simple and test drive it very thoroughly - any sounds of a "sugar cube in an empty Coffee takeaway cup" sounds are dangerous sounds, possibly even meaning that the dash may have to come out for more padding, or it could be the top speaker of the dash, which is a simple fix (though it can recur). The newer you buy the better - that way you have more original warranty left to help if it's bad! I'm dreading mine after the warranty is gone. I'd go for the post '56 platrs, with the boot/fuel release switches side by side (by the right knee).
Turn the stereo off for the first few miles of the drive. Pay particular attention to the centre console (gear stick area, handbrake area etc) by pushing against it and seeing what you hear and how much it flexes.
And finally, don't listen to salesman when he or she stats, "Naah - never heard of the rattling"...or "the LOC is full of whingers"...they are there to fleece you!
Also, don't forget - you do get 30 day no quibble exchnge for a used approved one and don't be scared to use it!
