A classic Ferrari is expected to become the world’s most expensive car after it was put up for sale at £45 million.The 1962 Ferrari 250 GTO – one of the world’s most sought after classic cars – was the second to roll off its production line and is one of only 36 ever made. “I have already had one offer on the car and know there will be interest. It will get you on the Ferrari 70th anniversary tour next year.”After the US election, people are going to be looking at investing in assets and this is a lot better than a painting on the wall.”Ferrari 250 GTOs normally only change hands behind closed doors, with a small number of brokers negotiating deals between the world’s richest car collectors. It was raced at Le Mans and Sebring and, despite being more than 50 years old, is capable of 0 to 60mph in around six seconds and a top speed of more than 170mph.The Ferrari has now come onto the open market for the first time in 20 years. John Collins, who runs Ascot-based Ferrari specialist Talacrest, is selling it for more than £45 million ($56 million).Mr Collins said: “I’ve been looking for a 250 GTO for a while and the opportunity came up with this one, which is the second GTO built.”It is a beautiful Ferrari, the Holy Grail of classic cars, and it has a great racing history having finished sixth overall at Le Mans and first in class at Sebring.

The car changed hands in 1975 when it was bought by a Mr Steve Griswold for $13,000 (£10,460) who restored the car before selling it in 1978 for $125,000 (£100,500).Over the past 40 years it has been shown at numerous Concours events around the world and was recently on display in a museum.With a £45 million asking price, the 250 GTO is 245 times more expensive than a brand-new Ferrari 488 and 4,500 times the price of a Ford Fiesta, Britain’s most popular car.
