I am about to pull the trigger on a GranCabrio 2011. I am just wondering if anyone has driven both the GT-S and the GranCabrio? Is the drive much different between the two cars. My hesitation to buy the GranCabrio has been its performance and questionable lack of top performance for a car in this class. The look and performance of the GT-S could sway me...any thoughts. I live in a nice weather town and currently drive a convertible M6 (BMW). Any thoughts on both sides would be appreciated. I have driven the Cabrio but not the GT-S, but if they are similar, would probably opt for Cabrio.
