I love the looks. All of it.
Yes, I see a lot of quattroporte in the proportions, but it's distinct enough, and they got the relation right.
I loved the old XJ, but, let's face it... I'm not the potential market. For potential buyers, the fact that the XJ was more cramped (okay... cozy... but they mean the same thing) than the competition and looked old hat for at least fifteen years of its life didn't help it overthrow the German establishment.
The new XJ exudes modernity, muscularity, and, from the looks of those interior pics... luxury. This is the way for Jaguar to go if it's going to survive the next twenty years.
Thank goodness they did away with the XF dual-monocle treatment... but isn't that ever the case? The S-Type looked strangely goofy compared to the XJ, too.
