Last night on the show they bought a Escort and pimped it out, and got to take it to the Ford Heritage Center (Centre?) when completed. In the background, was a white RS200 covered in plastic.
After tweeting my lust for it, whoever runs the @Wheeler_Dealers account replied back, stating that you can buy a rolling shell for around 2k pounds.
That's..... not bad. I can imagine the rest of the car does NOT come cheap, but that's a heck of a start to a rebuild, and would make for a good show if they ever has the cash and time to take on a project like that.
I've been trying to think of such a street legal unicorn rally or race car here in the US that you could buy that cheap, can't think of one.
