Just found this and I'm really excited to see this car in person. Looks like Buick is serious about the GS being a performance sedan. I'm really loving the Recaro seats. Here's the link with all the pics.
Just got my black/black regal turbo TO6 in June but Im already jealous of the GS owners. Couldnt wait though my Bonneville had 210,000 miles on her and she went that long without anything but routine maintenance so I didnt want to press my luck through this sweltering summer.
I saw a GS on the I696 in Southfield (SE Mich) with a manufacturer's plate, then saw one that had a owners plate the next day. They must be on the lots now or somebody from the Ren Cen got an employee discount and the first crack at one of new ones before they hit the streets.
Side note: anybody know how to stream media from a smart phone to the harman kardon system? my samsung infuse isnt picking up the speakers when i scan for bluetooth devices.
