MARKET ANALYSIS
Series JC (1990 to 1996)

The Eunos Cosmo (Series JC), which was manufactured globally between 1990 and 1995, represents the absolute zenith of Mazda's engineering audacity, with a total of 8,875 units produced exclusively for the Japanese market. This futuristic grand tourer achieved legendary status as the only production vehicle to ever feature the world-first triple-rotor 20B-REW engine (found in 3,550 units), while the more common 13B-RE twin-rotor version powered the remaining 5,325 units. In the 2026 Australian market, the Cosmo has transcended its "grey import" origins to become a blue-chip hallmark of the "Youngtimer" movement, with desirability exceptionally high for the 20B models due to their turbine-like smoothness and status as the world's first production cars with built-in GPS and a CRT touchscreen. The buyer pool in Australia is comprised of high-end rotary purists and technology collectors who are increasingly targeting the late-series "Type-E" (Elegant) variants, which featured a full leather-wrapped "floating" dashboard and a softer, long-distance suspension tune. Locally, market value has seen a significant surge for original, low-mileage examples that have avoided the common fate of being dismantled for engine swaps, as 2026 buyers prioritise cars with preserved electroluminescent displays and functional factory electronics. For the local enthusiast, the JC Cosmo is the ultimate expression of nineties optimism, offering a sophisticated and powerful alternative to the more frantic RX-7.
