Many people do, and those people often say their Miata or Mini are nearly as fun as their 911's etc. Not saying they're in the same 'league' but people are often surprised at how much fun they are to drive on the street. You can't wind out something like a GT3 for more than a few seconds without being at dangerous speeds - how fun is that? I get the whole 'g force' in your belly thing, but that soon gets old to me. I think that's how people get 'addicted' to power, turn to FI, etc. You just get used to it too fast, and it loses it's fun factor. I really enjoyed my early 911S- it had about 200hp, weighed about 2300lbs. Maybe low 14's in the 1/4 mile, no idea what the 'skidpad' of the thing was or any of those armchair-racer numbers. I don't care either - i could wind it out.... hear that beautiful flat 6 scream at 7300... zip around the corners and feel the rear end step out... tons of feedback through the wheel... really ENJOY the car without going over 100 mph like you need to in a GT3. The GT3 is too good, too fast. Again, my point was on the STREET. Track is a different story, but ask yourself what % of your driving time is on the track?
The NSX, btw, is fast, but IMHO is 'slow' enough to enjoy on the street
