Reliant Robin drivers, like Del Boy, were voted the least sexy

In second place were Ferrari drivers while BMW Z4 drivers came in third in the poll of 1,005 adults for insurer firstalternative.com.

But drivers of Reliant Robins - as favoured by Del Boy in TV's Only Fools and Horses - were voted the least sexy.

A third of motorists aged 18 to 24 said they would consider how sexy they looked in a car before buying it.

Some 65% of people questioned thought open-top cars were not as sexy as hard-tops.

The study also found that Ford Escort drivers were considered pretty unsexy, as were Austin Allegro and Skoda drivers.

Meanwhile, black was voted the sexiest colour for a car, but men also favoured red.

A quarter said what a person drove definitely added to their sex appeal.

First Alternative Chief Executive Colin Batabyal said: "Drivers may like to look good in their car but people need to consider the safety and insurance aspects.
