Eh sorry, but Eunos is a daughter company of mazda, and the NA roadsters/miata were sold as eunos roadster in japan.
there were a eunos cosmo too.
roadster is the name of the miata in japan, like the name was mx5 in europe.
it`s kind a like honda and acura, or nissan and datsun in the past.
mazda had eunos and infinity.
Looks like he is from The UK, they had The Mx-5, but during The years there have been imported quite alot of eunos roadsters. To OP: i would recomend that you post your questions on www.mx5nutz.com The UK forum, they can help you
