i honestly have no idea what the difference between an o-z edition and a regular gs....i have the o-z edition and the only visible thing i that i know of is the 16" o-z racing wheels...theyre alright but im gettin rid of mine for some 18's....the car caem stock with all the ground effects and the turbo wing...leather interior...and all the bells and whistles (extras like power everything, sunroof, etc)

 

yah i got 99 OZ and they are better then regular guages in my opinion but i agree i would just go for sum off ebay. get sum nicer one there anyway for prob cheaper then these stock ones lol.
