the ebay one this week was a good read and the owner is right up there in rallycross history,but i didn't like the look of it. the wheels looked pony and it was too clean i think either that or the wrong shade of white. there was loads of shenannigans with rs200's a genuine one that had a damaged chassis or tub etc would have replacement parts off a canibalised car ford themselves broke. i have seen disputes over rs200's years ago where a unregistered rs200 made by ford was dismissed by a berk in the iirc rs200 club.
you would have to certified dozy to buy a ex european rallycross championship rs200 that had competed in the most brutal of motorsports and then complain the car has been played with imo.
