An eye catching Delahaye Type 175S Roadster once owned by screen starlet Diana Dors is predicted to fetch a whopping $4 million when it goes under the hammer in the States later this month.

The bright turquoise sporty number is still a head turner today and is especially rare as it is one of only 51 175S Roadsters to be made. Despite the fact she couldn’t drive at the time, nor did she have a licence, the British born star acquired the luxury vehicle at the tender ago of just 17.

Made in 1949 by French manufacturer Delahaye, the sports car is a celebration of European design described by one expert as a “rolling sculpture” due to its outlandish appearance.

At some point it’s believed Dors sold the Roadster and it found its way to the US. The extravagant car has undergone intense restoration and is not back to its very best with a bright turquoise and white leather trim interior, and Perspex steering wheel.

As well as looking the business, the convertible also packs a punch when it comes to its performance. The 4 litre engine produces 165bhp and enables the 51-year-old car to reach estimated speeds of 75mph which is pretty respectable for a vehicle of this vintage.

The curvaceous car is due to be auctioned in California later this month and is expected to fetch between $4-$6 million.
