The XF has been a big success story for Jaguar since its release in 2007. It is now widely praised as one of the best executive cars on the market. It is wonderfully refined and thanks to its supple ride, it has the ability to allow the driver to tackle long motorway trips with ease. The spacious interior is thoroughly modern with leather, polished metal and mood lighting throughout the cabin giving it a real upmarket feel. If you want real power then the 5.0litre v8 XFR is the one to go for, but in the real world the diesel makes more sense, combining effortless power with good furl economy.
