The red wheels etc were done after it left Ford. It was built exactly the same as the standard coloured 3drs.
The Duke link is a red herring apparently, it was ordered by a Ford employee in the special vehicles operations section and he ticked the red box just to see, lo and behold it turned up! The chap came onto the RSOC board a few years ago and posted up some original pics from when it had been delivered.
Vince bought it from a Ford closed auction and kept it ever since. I had a good look over it at Combe, 70 odd thousand miles, it would resto nicely though.
I had heard Vince is poorly now and sold his race Capri but no doubt would want big bucks for it even in its current condition, he is a trader at the end of the day.
