Took the plunge, bought myself a used G6 on the weekend. I was actually banking on something smaller, but it came along at a good price, couldn't say no! First time I've ever owned GM metal, and that includes all the cars I owned back in Oz.
Nothing special to report really - 2006 base model sedan, grey/ blue, absolutely no mods/ upgrades/ enhancements. The best fun I've had driving in years, certainly since I moved to the US - a huge change from the family mini-van.
Purchased privately from one of my son's therapists.
