All of you are right. It's called Grayish Blue Metallic (Similar to the BMW purpleish blue), one of the 2 new colour for 2004, the other is Beige Metallic. Bought mine Grayish Blue B) in Oct last year and is even rarer than the limited edition grey. Personally is a good change from the usual safe colour of silver, blue, black, etc.

Had the same prob with my IS recently. Local agent could not fix the problem even after changing the suspension. Luckily the japanese engineers were in town when I sent in for the second time. Apparently, the insulation at the top of suspension tower was not "install" properly. Probelm solved.

My brand new IS started knocking when going over humps after 3 mths. Send in to the dealer here in Singapore and after toying around for 2 days , they gave up and changed the suspension anyway. Got the knock back after 1 day. Can anyone enlighten what could be the other causes?
