Robert,
I just had my front right fender backed into while I was in my car, so I was able to claim thru his insurance. My only battle now is to get his insurer to agree to replace the fender, they just want to repair it! As far as your question, your premium should not necessarily go up if it's going to be your first claim & you were not at fault. I guess the best thing to do is just ask your agent b/c everyone's experiences/situations albeit similar are handled a lot differently by various insurance policies. One thing's for sure though, take your NSX to Wagon Work in Crystal City, they're 1 of 8 Audi certified shops in the country to do aluminum body work & repair only highend imports. There are currently 2 NSXes there, one of them being mine. I'll let you see their work once I get my ride back!
