Preview: Porsche Panamera

After what has already been the most drawn-out model introduction ever (the initial Porsche sketches of the new model having been revealed in 2005), Porsche has finally released the first official rendering of its forthcoming Panamera sedan, set to be launched in 2009. Though the plan view doesn't show much of the new Porsche's design, the company says the features will 'include a wide and low body offering dynamic proportions and muscular design'. But while the grand tourer will have a 'compact overall look', the interior space is claimed to offer a brand-new experience of roominess, with two single seats and generous headroom at the rear allowing adults to sit in comfort.

How to buy a secondhand Ferrari 456

By Chris Chilton Motoring Issues 10 April 2009 10:00 The value of Ferrari’s big 2+2s have always gone down the tubes like used toilet roll, but not all have looked as beautiful as the 456, whose Pininfarina lines so cleverly disguise the car’s practicality. It can’t quite match a 612 for rear space but the back seats aren’t the joke you might expect and the ride quality is great – perfect for that imaginary trip to the south of France. Mike Wheeler of Surrey-based Rardley Motors (www.rardleymotors.co.uk) reckons he shifts more 456s than anyone else in the country and says the big coupés make real sense, but only if you service them at independents.
