Yes it is ... it's the XK150 Old Mill Special, presumably based on a '57 car and built in 1989.
Indeed it is, and I presume the same dates since those are mentioned on the caption. There doesn't seem to be anything else on the net about the car, although no doubt someone will say otherwise. I think the registration plate is German.
Something in the back of my memory links the "Old Mill" to a Jaguar specialist of yore, although I'm probably wrong.
Well found.
