Jaguar needs a winner, but we're not sure the XF fits the bill. The Aston Martin type styling that appeared in the XK appears here as well, but is too subtle to be picked up by the casual observer. In fact, that's the problem, there are design influences from several marques, but none prominent enough to give the XF any real style. With mixed reactions at the unveiling, the success of the 2009 Jaguar XF is now solely in the hands of the consumer. It's not that we think it's a bad car, it just doesn't live up to Jaguar's reputation. So, for the Leaper maker's sake, we hope buyers can get behind the XF more than we could.
