Thanks for your reply Paul
We really enjoyed the test drive, a very powerful but civilised car.
The dealer is fitting new tyres and reconditioned alloys. Mechanicals are barely audible with the roof closed, when open you get a gentle thrumming bass from the V8. The stereo is excellent, I did make sure all CD slots load and eject as per your suggestion as I've had them stick before in my IS200.
The car I'm looking at has a full service history and will have a Lexus one year warranty. The only hitch is my insurance company insist I will have to fit a tracker, not sure if all companies would insist on this.
All the best
Rob
