No productions numbers were ever made public. I understand that it may be something that Karmann has info on and the hope is they would provide them. There is an insurance company that insures them as collectible as they are out of production and there were a limited number of them made. The hitch is you have to have it as a pleasure car, so that if you and say a wife each have your daily driver cars the XF would be a third car at an address where there is only 2 license drivers. In our case our daughter has a license so even though she has never and will never drive the XF, we can't get the policy, which is a mega amount of savings on the cost of the premium. Shoot the kid doesn't even have a job, but it is true she "could" take a key and drive it without permission. Now that would be a crime, it's manual, she's never driven stick- can you image the transmission after that
