Range Rover has ripped the roof off its best-selling Evoque to produce the world's first compact 4x4 luxury cabriolet. The new £50,000 Chelsea tractor, pictured, is designed for fashionable, adventurous types who want wind-in-the-hair motoring, whether for an urban jungle shopping trip to Harrods and Harvey Nichols or family treks though the Cotswolds countryside.
