Hi all. I have just purchased a 2006 IS250 SE with 64k on the clock, full SH with all the extras (Nav, Rev camera, Levinson etc.) It is a manual which is a change as my last 3 cars have been auto. When i have driven manuals before, the norm was to change to 3rd at 20, 4th at 30 and so on. This Lexus however seems fine going in to 4th at around 27, 5th at 31 and 6th at 35-36. No rumble, but very high MPG figures. Is this doing the car no good? Had a new clutch fitted at 56k so shouldn't need doing in my ownership (i hope)
