We have a 2019 XJL Supercharged 1 of 300 for the US market only. I am trying to find out which number we have. I have contacted Jaguar Headquarters, the dealer and no help. So I emailed the gentleman from Car and Driver Clifford Atiyeh that wrote the article dated Nov. 19, 2019. Clifford answered me back and suggested that I put the question on this forum, because Jaguar is very tight lip about the numbering.
Thank you for any help

 

This is the nearest that you will be able to get to the numbers. We are working on it. But, we only have a limited amount of data being given to us. If you have some, please pass it on. We can possibly fill in some blanks working together.
