One amazing thing about the 991 is the acceleration for a car that doesn't have that much HP relative to many of its competitors. I know the weight is low, PDK is great but still... it's quarter mile time is VERY fast. It would walk many higher powered cars.
Acceleration, handling, nicer interior now... it is a fantastic car. I would take the M3 for the DDer and the 991 for the weekend/track toy. Or better yet, wait for the GT3 to be released
