2008 Jaguar XJ Preview – Geneva Auto Show: There’s a link between cars and plastic surgery addicts – neither is able to grow old gracefully. Addicts don’t appreciate their natural beauty; the constant call for improvement leads to some disproportionate mess that scares children and puppies. Cars, unfortunately, are at the mercy of the buying public and designers, so every few years they go under the knife. The operations vary from severe to a mild augmentation, as is the case with the 2008 Jaguar XJ. This iconic British sedan rolled away relatively unscathed, with its overall shape and potent powerplants intact, but that gratuitous growth of a front bumper is like a pimple on the face of Gisele.
