This map lists shops known to have considerable NSX experience. It is based entirely on input from NSX owners in the region. Shops cannot directly request to be added to the list, nor can they pay to be added. If you have a shop and would like to be on the list, get lots of satisfied NSX customers to post positive reviews of your business in the message forums and after a couple years you may develop enough of a reputation to be listed.
This is only a listing, not an endorsement. Do your homework before doing business.
