Pretty cool, for the first time ever, not too mention the first time since I have owned my GXP (March 2012), I saw another GXP. Ok I have spotted a few GXP's at other car shows and events, but never a random sighting on the street.
I briefly spoke with the owner too. Original owner and daily driver, like mine is as well. Red, sunroof, black interior and automatic; and appeared all stock. By contrast mine is white, sunroof, red/black interior and manual. Plus Holden rear and wheel badges.
Pretty cool and it made my day.
