That looks like imperial to me - I think extreme blue came on the facelift cars, and the one in the add is a prefacelift with the MY03 bumpers fitted. :)
 
The cars in these threads are Imperial Blue, which is a dark metallic blue

Loved my imperial blue, lovely colour. There is an extreme blue thread about - have a look and you can see the difference between them.
