It’s still the same thing the GTO introduced to the america’s is basically 2 years behind body style wise i.e the middle east and australia have the 2007 model style by now, but the GTO looks like first kind of lumina SS i.e from 2000 to 2003.
here i’ll post up pics so guys can compare, trust me i know about them i owned a 2003 Lumina SS it was a Holden with Chevrolet badges.
Well below are pictures of my Lumina SS in Dubai, although i think my cousin that bastard sold it after i left.lol
Anyways look at it other than the badges the GTO looks like the older lumina SS,i.e the one shown in black below. The lumina SS were built prior to the year 2000 so yea Lumina SS OWNS the GTO (new one).lol
Therefore the 2006 on wards GTO is the old body shell from lumina SS which was connectively developed by Holden and Chevrolet, Pontiac joined the game later, as the GTO to the American Market.
Now if you look below, the body style Holden Commodore SS and Chevrolet Lumina SS this was up to i think 2006, and for 2007 the body has changed even more.
If this is still not what you saw, it probably is.lol you could have seen the HOLDEN CREWMAN SS, its a Holden commodore SS pickup.
