Thanks for the reply - very interesting! I've often wondered whether this was a "real" RS200 or a replica (in some form). Pity that the car isn't used in competition by the Doran's at the moment, though I know it was borrowed by Ollie O'Donovan for the last round of the BRC this year, so hopefully it'll be used in competition again next year.
I'm at Lydden for most rallycross events and I always spend a moment (or two...

) looking at this car if its in the paddock. It was this particular RS200 that caught my eye a few years ago and encouraged me to go and check out rallycross, purely to see an RS200 being used in competition - I've been hooked on the sport ever since!
