Vauxhall Cascada: Official

The new 2013 Vauxhall Cascada – a full size convertible and the modern version of the Astra Twin Top – has been revealed. For some reason best known to Vauxhall, they chose not to debut the Cascada at the Paris Motor Show – perhaps to give the new Adam its moment in the sun – but now we get Vauxhall’s latest model in its revised line-up. The Cascada is a proper full size, four seat convertible – it’s only a couple of inches shorter than a Mercedes E Class Cabriolet – and has its underpinnings based on elements from both the Insignia and Astra and comes with a folding fabric roof instead of the tin-top folding roof in the Twin Top which can be raised and lowered in 17 seconds at speeds of up to 30mph.
