Be wary of the XJL especially if it is petrol. The USA site reports that the engines are giving problems from damaged crankshafts to water pump failures and the L is so long the body flexes and the plastic trim cracks. I have the short wheelbase (big enough for UK roads) and it is the 3.0 diesel and can say it has been completly reliable since I picked it up and have done 7000 miles in 3 months and the car had 19k on the clock when I got it. Main dealer services, not worth the paper they are written on!
