Hi everyone,
Just came across this post and it seems I'm in exactly the same position as Amz was 6 years ago!
Got hold of an IS200 Sport at the weekend (also blue) and really wondering where to begin. So far I've only done a few hundred miles on the motorway in it, but agree it's a bit sluggish in the lower range.
Amz, what did you do to your Lexus and how did you get on? Looks like you have very similar taste to me as I also want it to be a bit more responsive, sound a lot better, and some subtle aesthetic mods.
