- The On-line Registry of Miatas and Their Proud Owners - (If something doesn't apply to you or you just don't want it to be everybody's business, leave it blank-The only items required are your name and your Miata's model information.) We're sorry, but the registry is currently undergoing maintenance, because my sister in law is a byatch. Sorry for the inconvenience. If any options/colors/models are missing, or you just have comments or questions about The M-Registry, Please let me know! Back to the Registry:
