The Alfa Romeo Spider (105/115 series) is a roadster produced by the Italian manufacturer Alfa Romeo from 1966 to 1993—with small run of 1994 models for the North American market. The Spider remained in production for almost three decades with only minor aesthetic and mechanical changes. The first three series were assembled by Pininfarina in Grugliasco and the fourth series in San Giorgio Canavese. The last Spider was produced in April 1993—the last rear wheel drive Alfa Romeo before the Alfa Romeo 8C Competizione of 2007.In May 2012, Fiat announced an agreement with Mazda to co-develop a new Spider for 2015 based on the Mazda MX-5 platform. The agreement was finalized in January 2013.The Spider nameplate originates from the English word "speeder", a two-person open horse-carriage.[citation needed]
