Is the convertible heading into the sunset?

Sophistication, freedom, rebellion or just the simple joy of taking to the open road with the wind in your hair. The convertible car used to represent all of these. But over the past two decades sales have collapsed, and its future seems deeply uncertain. So what's gone wrong?

In the 1950s and 60s, owning a convertible showed you had style. They were what the celebrities of the era were seen in.

When Hollywood deities Grace Kelly and Cary Grant were shown cruising along the French Riviera in a beautiful, sleek Sunbeam Alpine in To Catch a Thief, for example, they epitomised silver-screen elegance and savoir-faire.

Later films like The Graduate and Thelma and Louise helped cement the open top car's position as a symbol of escapism and rebellion for new generations.

For a while, convertibles were what people dreamed of buying, and manufacturers were happy to make them.

Yet today, the convertible is looking like an endangered species in the UK.

Over the past 20 years, sales of new open-tops have fallen by nearly 90%, from 109,171 in 2005 to just 11,484 last year, according to the Society of Motor Manufacturers and Traders.

That decline has coincided with a dramatic rise in Sports Utility Vehicles, or SUVs – large cars with at least a passing resemblance to four-wheel-drive off road vehicles. Last year they accounted for 59% of car sales across Europe, according to the research company Dataforce GmbH.
