I'm going for the bucket.
1) Most bolts are coated to prevent galvanic action between aluminum and iron.
2) The gas tank is in the center so the balance is not affected by how much gas there is.
3) Many different aluminum alloys were used for rigidity in body and chassis.
4) The car comes with an electric air pump to fill the full size collapsible spare tire.
5) Since the radiator is in the front, coolant runs from the middle to the front of the car which requires bleeder valves to fully drain the system.
6) The glass behind the passengers is double glazed for sound insulation.
7) The ABS is a 4 channel system [ most cars are three].
8) There is a clutch damper system to soften engagement.
9) The trunk was designed to fit enough for 2 people for a weekend.
10) If you are delivering pizza, the trunk will keep it warm.
11) There is no make-up mirror. Make-up mirrors do not improve performance.
Great list. I think we can add the following:
12) First use of VTEC in North America
13) First use of Titanium connecting rods
14) Last minute switch from SOHC to DOHC required extending the body by 30 mm
15) Final suspension tuning by F1 legend Ayrton Senna at Nurburgring and Suzuka race tracks
16) Assembled by hand in Japan in a plant specifically built for it
17) Ignition key made of 'unobtainium' ;-))
18) Less than 9000 sold in the US from '91 to '05 model years
19) There is a strong owner's club (NSXCA) and active online participation at NSXPrime web site
20) Early models had a black roof to mimic the cab forward canopy on a fighter jet
21) Chassis stiffness was modelled with a Cray supercomputer
22) Forged aluminum suspension arms
23) 8000RPM redline; 168 mph top speed
24) Unique asymmetric tires designed specifically for the car by Yokohama
