I have a 1991 automatic:
1. Better manual shifting for automatic or SMG - I plan to upgrade to a 97 auto, but the shift lever isn't like paddles. Better (more aggressive?) shifting algorithm - my 1989 MR-2 did better than NSX in auto mode
2. I posted before the climate control needs help. It knows int/ext temp, etc. and should display it. It blows cold air too soon in winter (if the air from the vent isn't a few degrees warmer than internal air, why blow it?), it stops too soon in summer (if the interior is hot, the air temp being right isn't enough). The controls on the climate control are great, except it needs an ON button as well as AUTO that remembers how it was set when turned off.
3. Interior displays need to adjust brightness based on ambient light, not headlight switch - running in the rain in daytime makes the radio/clock impossible to see.
4. tilt adjustable steering wheel (missed from Eclipse)
5. memory for seats (takes me forever to reset seat after my wife drives every Sunday)
6. smartenna feature (I never listen to radio)
7. in-dash cd changer w/MP3/WMA and standard double DIN space - don't do integrated stereo (Eclipse had clock/radio display built-in - not very useful for aftermarket stereo)
8. hands free cell option that interfaces to bluetooth cell phone
9. builtin bluetooth gps with optional nav system (so I can use my laptop
)
10. auto up and down on all windows - maybe auto reset windows when door closes (roll down 1/2 inch then up) like merc/bmw did for better seal?
11. heads up display
12. a little more cabin storage (maybe door pockets?)
13. better door stop positions - with the long door needs a harder intermediate stop (or swing up doors)
14. heated/cooled perforated seats (they are already perfect for long trips on comfort)
Overall, I think journalists don't know what they want - they complain the NSX has a dated interior, then say new cars have too many tiny buttons, too much electronics, iDrive, etc. I think the NSX has a great and very ergonomic interior but everything can use more features
I'm sure I can come up with some more...
