Introduced in 1953, the Ferrari 250 quickly became the company’s most successful vehicle lineup. It included everything from road-legal grand tourers to the 250 Testa Rossa and 250 LM race cars. More importantly, the range spawned the iconic 250 GTO, currently the most expensive Ferrari ever auctioned (as of August 20, 2014). The 250 line came to an end in 1964, when it was replaced by two distinct families, the 275 and 330. While the 275 GTB/C stepped in to substitute the 250 GTO, the 275 GTB/4 took center stage as Ferrari’s new flagship model.
