Dave,
Welcome...as for your question, No you will not regret getting an NSX. You might just use that 07 s2k as a daily beater once you get an NSX. If you are looking into buying an NSX most would probably tell you to pick up a 97+ because it has all the NA2 specs. (3.2 liter, 6 speed, targa, and you save a few $$$ from having to spend that extra on the 02+ comestics), but if you are planning to track the car, than I think a 91-94 coupe will suite you best.
There are many NSX owners here who have both NSX and S2k. No complaint on either car, but I'm sure they will all tell you that the NSX is by far a much more fun driving experience.
good luck on your search....
I would like to track it..but which year is better...i guess the newer one right? so like 94? but is there really a big diff from 91-94?
or does this pretty much sum it up?
