I have been on a mission for the past 2 months trying to find a G8 GT. And i finally found one and brought it home today!!
2009 G8 GT Sport Package with Axle back SLP mufflers.
Has 83k on it and the guy that owned it before me took AWESOME care of it!
I had to drive 300miles one way to Wisconsin to get it but IMO it was well worth it!
