Typically this would be asked in the Southwest Region Forum, but I'm sure it'll get moved when Lud has time.
Depends on how close you are looking. If you don't know of them already, there are two well-known, reputable service locations within reasonable driving distance to you.
Autowave in Huntington Beach
Power Acura South Bay in Torrance (speak with Jon Martin)
Both of these shops have provided superb service for NSX'ers in that region and both are also sponsors of NSXPO '05 this year! :smile: While not really close to you, these shops are easily worth the drive.
Good Luck!
