Have looked into rs6's and 996's but the 996 without the turbo would feel a bit slugish.Ive drove my firends 996 and he drove mine and he was positive that in a straight line drag the 32 was a quicker car, not ruling a porker out though.
The 996 3.4 is quicker in a straight line than a C32 - just depends on who's driving . The 32 feels quicker as lower speeds because of the inertia involved.
