[Twitch Massacre]

Well, given the longer wheelbase the GC does feel slightly more grounded than the Coupe. I find the rear seats in the Coupe to be usable only for petite women or small children. If you have someone considerably tall sitting upfront in the Coupe, by the time they adjust to a comfortable sitting position, the space behind them will have nearly evaporated. Regardless I went with the Coupe as I very rarely have more than one passenger, and the difference in ride quality overall is very small. The M6 in general is just a very comfortable car. I also really like how coupes look.
