I never planned on daily driving the NSX but when I first got it, I couldn't help driving it everyday.
After that wore off (took a while), I started road racing my daily driver which made it hard to use a daily driver - so I divided my time between the NSX and the road racing beater.
Now, I have a comfortable luxury SUV, the road racer (which is in much better shape now), and the NSX.
I actually prefer to have the NSX as a toy and NOT as a daily driver. There is just no way you can really enjoy the car when you use it to haul groceries or sit in traffic with it. It's also not as fun when it's even just a little bit dirty and you can't keep it spotless when it's a daily driver.
I can't imagine having the NSX as my only car. Sorry - but I could never feel good about having molding sticking out of the t-top area of my NSX.
I just love the fact that I can uncover the NSX, fire it up, and go for a great drive, come home, then cover it back up.
