Alfa Romeo was still close to racing primacy in 1965, and this beautiful 2600 Spider shows just how good Alfa was at their craft. The 2600 Spider was the last Alfa Romeo to have the traditional twin-cam inline-six, the engine configuration Alfa was known for since the 1920s, and billed as a Continent-crossing grand tourer. This 2600 Spider was discovered in California and has had only one owner since new. The car will go up for auction in May as part of Gooding & Co.’s Geared Online event.
