Ferrari most expensive car sold in Britain at over £24m In 2009 another Ferrari 250 Testa Rossa sold for £8 million, a fraction of the price for the latest model. Mr Hartley said: "I can confirm that the car has sold, although due to client confidentiality we will not disclose the buyer or the price achieved. The Ferrari Testa Rossa, a 1957 model and the second prototype ever built (SWNS) This Ferrari is without question one of the most important cars on the planet if not the most important because of its originality. While I won't go into the terms of the sale, I am sure it will prove to be a great investment for the new owner. Now it is done, my only disappointment is the fact I don't think it can ever be bettered as I truly think it is the greatest car in the world. The Ferrari 250 Testa Rossa, which is Italian for 'red head', is powered by a 3-litre V12 engine which develops 300bhp. This gives the road-legal race car a 0-60mph time of around six seconds and a top speed of 167mph. It was the second prototype and factory team car for two seasons with Ferrari then making a further 19 customer cars. Marcel Massini, a Ferrari historian with an encyclopedic knowledge of the famous marque, described the model as "one of the top five Ferraris on the planet." He said: "It is so valuable because it is totally unmolested and not restored, genuine and very original. It also comes with a fantastic history which is most important. I believe the Ferrari market will continue to go up as more and more wealthy people need to reinvest their cash but there are not many more top quality cars available. It's simple supply and demand. Classic cars as hard assets are just one of several asset classes nowaday. The Ferrari Testa Rossa appeared on the racetrack in 1957 at Le Mans and ran as high as second place, but did not finish the race.
