My first NSX was my daily driver for years, I ended up with ver 100k and the car was about 8 years old at the time. At the time, my girlfriend (now wife and two kids) talk about the car all the time. We had a great time driving around San Francisco and commuting to work everyday. Four weeks ago, I came back to being an NSX owner.
However, before I looked at the NSX, I looked at a Noble M12. I was looking for something that was "just" practical but exotic. The M12 was quite the performer, but no trunk whatsoever and the interior wasn't too refined. Nice looking car though!!!
I remember putting my brief case and gym bag in the NSX, grocery shopping and running errands without any problems. I was paranoid about someone giving me door dings, but whenever it happened, I just had them repaired an went on with enjoying the car.
Honestly, I believe that the most affordable, reliable and ultra performance exotic would be a turbocharged NSX.
If you could find a decent 91 for 30k, you could have the motor, turbo system, rims, suspension and probably a few other things for 55k. This would get you a super head turner that packs over 500hp to the wheel.
I drive my car as much as possible and I don't worry too much about the mileage. It's irrelevant to me as LIFE IS TOO SHORT TO NOT ENJOY IT NOW!!!
