Formed in 1967, the register is concerned with keeping track of as many XKs as possible.

With an initial history of running competition events for XK owners (the car values were a lot less in the late sixties and early seventies!).

Today the register provides a number of weekend breaks specifically targeted to provide the opportunity to drive through spectacular scenery and encourage sociability between XK owners and their partners. An International day brings together overseas XK owners and is the opportunity to run the annual concours to choose the XK to go forward to Champion of Champions.
