Did you see the Buick GNX half time show? Damn, using a circus clown car routine where an unreal amount of people come jumping out of small vehicle, that's a good trick for a half time show! And the incredible amount of good publicity that the Buick GN/GNX has had recently continues

I saw the car on the stage before the halftime show, and wondered what that was about... 

Road and Track dug into it, and reports that GNX is the latest album name, for Kendrick Lamar who  was brought home from the hospital when born, in a Regal (base of the GN and GNX)
