Aerosmith frontman and American Idol Judge Steven Tyler has decided to splash out some of his hard earned cash on the Worlds fastest convertible car.

The wacky scraggily haired rocker forked out a whopping £700,000 on the Hennessey Venom GT Spyder which can propel ins sexy body work up to 200mph in an amazing 15.9 seconds. Steven, father to Hollywood actress Liv Tyler, is the first person in the World to request a convertible version of the motor.

Venom GT Spyder boss, John Hennessey spoke about Steven’s unique request, he said, ”Steven came to us last year and asked if we could build his Venom GT as a roadster. We had to make a few structural changes to our integrated rollcage in order to be able to fit the removable top. This increased the weight of our vehicle by about 30 lbs to a curb weight of 2,743 lbs (1,244 kilograms). We decided to increase the Venom GTs power to 1,244 bhp to maintain our 1 horsepower per 1 kilogram power to weight ratio.”

It looks as though The ‘Demon Of Screamin’ will soon become ‘The Demon Of Speedin’!
