I wholeheartedly agree with Marc (SpeedDemon). I had an NSX as my only daily driver for several years and found it to be excellent. No mechanical issues, decent milage, easy to drive in traffic and comfortable on long trips. The trunk is a bit small, but it is as large and functional as that on any other sports car. Occasionally, you may have to be a bit creative on caring large items (Marc had to carry home a box with part of the turbo kit I sold him in the passenger seat, for example), but it is not a real issue in my opinion. Just know you will not be able to run down to The Home Depot and drag home a load of plywood.
On a philosophical note, I think that is what the designers intended - a performance car you could live with everyday. Here in Texas, we get all kinds of weather, except snow, and I had no hesitation driving my NSX in any conditions. Just take the same care in the ran that you would with any other high hp/low weight car.
Enjoy life; you are not going to end up on your death bed with your only regret being 'damn, I wish my car had a bigger trunk.'
