Mazdaspeed MX-5 Coupe: 350 Built, Fixed Hardtop

The Mazdaspeed MX-5 Coupe is a 2004 limited-edition MX-5 (NB8C generation) built by Mazdaspeed, Mazda's in-house tuning division. Unlike the production NB MX-5 which was only available as a roadster with a soft top, the Mazdaspeed Coupe featured a hardtop roof permanently welded to the body. Only 350 were ever built, making it one of the rarest Mazda production cars ever sold.

The NB MX-5 Platform

The base car was the NB (second-generation) Mazda MX-5 Miata, produced from 1998 to 2005. The NB had the same fundamental layout as the original NA Miata — front-engine, rear-wheel-drive, 2-seat roadster. The Mazdaspeed Coupe modification transformed this into a fixed-roof hardtop.

The Coupe Conversion

Mazdaspeed engineers designed a permanent hardtop that replaced the folding soft top. Key changes:

Roof: Fixed steel hardtop welded to the body
Body rigidity: 25% stiffer than the roadster due to the fixed roof
B-pillars: Modified to support the roof
Rear window: Fixed glass instead of the roadster's plastic window
Weight: Approximately 50 kg heavier than the standard NB

The interior was unchanged from the standard NB — same seats, same dashboard, same instruments.

The Engine

The Mazdaspeed Coupe used the standard NB8C's 1.8L BP-ZE 4-cylinder engine, producing 160 PS. Mazdaspeed also sold a turbocharged version (the "Mazdaspeed Miata" of 2004-2005) that made 178 hp — but the fixed-roof Coupe version of the turbo variant is rarer.

Production: Only 350 Ever Built

Total Mazdaspeed MX-5 Coupe production: exactly 350 units between 2003 and 2004. All sold in Japan through Mazda's Mazdaspeed dealer network. The limited production was part of Mazda's strategy to create a collectible, desirable car that would promote the Mazdaspeed brand.

Today's Market

Surviving Mazdaspeed MX-5 Coupes are now extremely rare:

Clean examples: $30,000-$50,000 (compared to $15,000-$25,000 for a standard NB)
Low-mileage examples: $50,000-$80,000
Mint concours examples: $80,000+

The Coupe is more valuable than the standard NB because of its rarity and the unique roofline.

Legacy

The Mazdaspeed MX-5 Coupe is one of Mazda's most unusual production car experiments. It's the only MX-5 ever sold with a fixed roof from the factory. The standard MX-5 has always been a roadster; the Coupe was a deliberate departure meant to create a collectible, distinctive variant.

For Miata collectors, the Mazdaspeed Coupe is a reminder that Mazdaspeed could build unique, limited-edition cars when the market justified it. With only 350 built, it's one of the rarest Mazdas of the modern era.
