Personally i stopped bringing my NSX to the Honda dealer, or any garage for that matter.
I simply do not believe in the skills of the mechanics (sorry for that, offcourse there are exceptions). The best 'NSX' mechanic here in Holland worked on my NSX, and i found it a very bad experience, though other NSX owners did find the services this dealer offered oke (there out of business now). I'm probably to anal about my car (if complaining about stripped bolts and scratches is being anal).
I do the work myself now. From the regular oilchange, doing the brakes, fixing electronic faults, replacing the A/C condesor in the dash, to the more challenged installation of shortgears (how more difficult can it get?).
Without the existance of PRIME or NXSC, WOW, without the online manual, i wouldn't have been able to do most of it, especially since a lot of procedures are different from other cars.

If you guys have questions about doing the more challenged things yourself, mail Larry Bastanza, he does al the work himself as well, and knows a great deal from experience.
