@Aero2000 1975 would probably be a better year to suggest as by 1978 the car was on its way out with only a relative handful built and sold that year. Although they are regarded as classics now I remember at the time they had a poor reputation for reliability, thirst, rust and collapsing in value - British Leyland cars from this period were sadly very badly built. The roof lacked rigidity. Now increasing in value because relatively few were sold and most of those dissolved into rust leaving few survivors.
There was a race version prepared by Broadspeed for the ETCC, but they struggled with braking on the racers - I never understood at the time why they didn't race the XJS instead, but the XJ12 Coupe was what Leyland insisted on.

@StarLight the car in your picture is a Daimler as we can see from the fluting of the radiator grille, but you probably just picked it for the colour.
