I live in lane cove mate, have not seen one. Dark blue is a very rare colour from factory. I believe the GTR which came in blue in the R32 was only made 100 times, GTST would be no doubt the same. Unless sprayed but dunno why you would spray it blue.
You sure its a R32?
Saying that its not hard or expensive to make a R32,33 or 34 move abit faster than 13's Unlike the Porka which is quite costly. Ive smoked alot of Porkas.
