The Mazda MX-5 (NA) (sold in Japan as the Eunos Roadster (ユーノス・ロードスター, Yūnosu Rōdosutā) and in North America as the Mazda MX-5 Miata) is the first generation of the Mazda MX-5 manufactured from 1989 to 1997. Inspired by the post-war era British sports cars, the MX-5 rejuvenated interest in roadsters after the demise of cars such as the MG B and Triumph Spitfire. Since its debut, the MX-5 has won numerous automotive awards and has become the world's best selling sports car. The MX-5 was unveiled at the Chicago Auto Show on February 10, 1989, with a price tag of US$14,000. The MX-5, with production code NA, was made available for delivery to buyers worldwide in the following dates: May 1989 (as a 1990 model) in the US and Canada; September 1, 1989 in Japan; and 1990 in Europe. An optional hardtop was made available at the same time, in sheet moulding compound (SMC). Demand initially outstripped production, fueled by enthusiastic press reviews. In Japan, the car was not badged as a Mazda, as the company was experimenting with the creation of different marques for deluxe models, similar to Nissan's Infiniti, Honda's Acura and Toyota's Lexus. Instead, the Mazda MX-5 was sold as the Eunos Roadster in Japan, and was joined by the MX-3/AZ-3/Eunos Presso (based on Japanese Mazda dealerships). The exterior dimensions and the engine displacement were also in compliance with Japanese compact car regulation.
