Years ago, no one could have imagined how collectible the little Mazda RX-3 would become.

They were consumer goods, left at the tip without a second thought once many original owners had their use. Those that did end up on the secondhand market were almost all modified in some way thanks to decades as cheap performance weapons. Take into further account, the cars that ended up tress, or simply rusted away as all 1970s cars did – history has shown that the humble little rotary is one serious piece of rare metal; and is now one of the hottest properties in Japanese collectibles.

When you look back at the history of Wankel engine cars, you could be forgiven for wondering what in hell people were thinking. The promise of a smoother, more compact, and quick-revving powerplant, delivering more horses per cubic inch than a conventional four-stroke reciprocating engine was attractive, but not necessarily compelling.

As pioneers such as NSU discovered, there were as many downsides as up to the then comparatively new technology. One was gaining reliability – chewed-out rotor seals was an issue – and the other was overcoming the buying public’s natural suspicion of any technology that was relatively unproven.

Mazda was really the only company that comprehensively overcame those issues. One of its tactics was to provide ample reassurance. In America, the company offered a five-year or 75,000 mile (120,000km) warranty on engines, way back in the seventies.

If any car represents the coming of age of the rotary, it’s the RX-3 in its almost baffling array of variants. Sold as the Savanna in other markets, the series based on the Grand Familia platform rolled into the market in 1971 (March 1972 in Australia) powered by the 10A twin-rotor engine.
