I want to sell a car which I believe falls into the "unroadworthy" category. Am I correct in thinking that I can sell it to a private individual, as long as I clearly state that the car is unroadworthy in the advert and get them to sign a statement at the time of sale accepting this fact?

If I can sell it under the circumstances described above, does the car absolutely have to be taken off my land without being driven (which would still be possible)? Or could I sell it to a private individual who wishes to drive the car away, if they sign a statement that they accept it is unroadworthy, have arranged insurance, and are taking it to a pre-arranged MOT test?
