Of the nine Acura dealers in the Chicago area, there are two that do a lot of NSX service: Woodfield Acura in Hoffman Estates, and Pauly Acura in Highland Park. Both have two highly-experienced NSX techs, and more often than not, you can find them working on an NSX. You can trust them with even the most complicated NSX services, such as clutch replacements, timing belt replacements, major services, etc.
The same can be said of Acura of Brookfield. AoB is also likely to be somewhat less expensive than the other two dealers. However, it is a hundred miles each way, which is not exactly convenient for most folks, even with a loaner car for larger jobs (which means driving two round trips there, of course).
When I'm doing something that is specific to racetrack use and/or aftermarket modifications, I'm likely to make the long drive to Milwaukee for Acura of Brookfield, which has more experience in these particular areas than the Chicago-area dealers. In fact, if I wanted to do something like an aftermarket supercharger installation, that's the only place I would go.
For most other NSX service, I stick to one of the two places in the Chicago area, simply because of the distance.
I would trust any of the three to service my NSX properly. And so can you.
