Apparently the fire was due to an electric problem - a common phrase in the world of Italian cars - when a short-circuit near the battery occurred, sending sparks to surrounding materials. The poor car was then engulfed in flames and burnt crispier than a deep-fried potato chip in no time.
It's the first report we've heard of an Alfa 8C suffering from such problems so no recall matters are currently stirring. It's a shame though that one of these beautiful coupes is now gone because now there's only 499 of them left on the planet.
