Take it to a body shop that has experience with the NSX. They all give free estimates. And they can usually spot damage that an amateur would never notice. If the estimate is so low that you don't want to file an insurance claim (or if you don't even want to fix it), you don't have to.
I don't know of any in the city, but Schaumburg Auto Body in Roselle has fixed quite a few NSXs. Including mine, when I hit a truck tire retread in Indiana :frown:
If your car needs any mechanical work, Schaumburg Auto Body is not far from Woodfield Acura, where Ted is the most experienced NSX tech in the Chicago area. Body shops can fix mechanical problems that result from road incidents too, but for most mechanical work, I'd give it to Ted. If needed, they can get the car back and forth between the two for work; I believe SAB gets their parts from Woodfield Acura.
