Bentley Continental GTC Convertible

Bentley boasts of a top speed of 195mph for the GTC - unusual in this ‘artificially limited to 155mph' world. The GTC shares its coupe brethren's glorious 621bhp 6.0-litre, 12-cylinder engine and acceleration is unsurprisingly quick - 0-60mph in 3.9secs. Whatever speed you're travelling, there's always stacks of power just a prod of the throttle away.
Given the extra strengthening and weight the GTC has to prevent the body wobbling, ride quality is superb - this is a seriously comforting car. Handling is pretty much on a par with the coupe, too, so it's secure and rewarding. The four-wheel-drive system provides bags of traction, but in no way diminishes the fun factor.
With the hood down, there's little buffeting unless you're going at speeds above the legal limit. With the hood up, however, there's a disappointing amount of wind noise, in spite of a plush, three-layer hood. There's a fair amount of rumble from those big tyres, too.
