I would not propose to enter into a puerile arguement about which is the quickest, rather let the "ring times" and "stig" times speak for themselves.
I am asking for a reasoned opinion, not prejudice.
Its my belief that the NSX would be a much more "relaxed" car at speed on B roads compared with my Corvette's, plus the steering wheel position helps, my SL AMG being much more of a GT.
In terms of luggage capacity, there is obviously no comparison.
I have looked at a number of NSX's, and would place the SL in 1st position re quality of build/cockpit ambiance etc, and the Corvette last.
The service requirements of Corvettes are interesting, only oil/filters fluid changes until 100k miles. Perhaps its because at 75mph, its turning over 1600revs.
All three cars have their strengths and appeal to differing requirements, the NSX is just the one car that I have allways yearned for, and its my intention to grow old disgracefully.
I currently have my eye on a number of late series cars, what is involved in hardware upgrading to "R" spec, and at what cost, indeed is there any point, the base car being good enough anyway.
Reasoned opinions please, not red mist prejudice.
