When you have children, you need a car with lots of interior space that you can fill quickly and easily with kids and stuff. The 2013 Jaguar XJL, the long wheelbase version of the XJ, has this sought-after wealth of space, but it’s not a great family car.
The XJL’s 5 additional inches of rear legroom encourages lounging and luxuriating, which in my experience are things most appreciated by adults. You can stuff your children and their things into this sedan, but don’t expect them to grasp its true beauty.
