WATCH: The fastest power-folding car roofs you can find

Getting the roof down quickly on a convertible car is very important on a hot summer's day, or even on a cooler day here at home in SA. These are the five fastest roofs in motoring.

The Porsche 911 Cabriolet and the Jaguar F-Type Convertible both fold down ini just 12 seconds.

The Audi TT Roadster takes 10 seconds while the Porsche 718 Boxster goes down in nine seconds.

And the fastest of the lot? The Ford Mustang Convertible takes an amazing seven seconds.
