James,
I have pondered the same thing as you many many times, and even though I still have my faithfull 1992 NSX, when and IF I ever decide its time to finally put the old thing to sleep, the only car that turns my head just now is the Aston Martin DB9, (even though I would love a Lagonda...a car that's so **** it's fantastic -well in my eyes).
However I've just shelled out for a 06 plate supercharged Range rover sport, so the ol' NSX stays for now.
Happy hunting (although you know you'll just go full circle and end up with ANOTHER NSX after what ever you decide to go for!!!)
