The G6 is completely stock besides some Alpine component speakers. The formula on the other hand has come a loooong way, haha.
Let's see... I got it in May of 2005, it was pretty rough looking. I replaced the stock hood with the firehawk hood and had the car repainted, added the gunmetal ZR1 wheels, got new tail lights, changed the cd player, speakers and added a stealth mount sub. It just got a brand new lt1 crate motor straight from the factory... Other mods include... Mezierre electric water pump, K&N Cold Air Intake, BMR rear lower control arms, Hotckis adjustable panhard rod, Pacesetter Long Tube headers and off road y pipe, Ravin muffler and I'm sure I'm forgetting something!
Soon to be added will be new window tint, brand new carpet and some Black collectors edition leather seats.
Oh and the color of the formula is called Purple Pearl Metallic... It's like a gunmetalish purple, haha.
