Oh... almost forgot. If you do decide to eBay, I had a very, very strong response on a car I sold by putting a video test drive (hosted on Youtube) right in the eBay listing. It was an old, old car, and people seemed reassured to be able to see on the video that it started easily, ran, and drove well.

That might also reassure anyone who thinks yours doesn't have an MOT because it wouldn't pass.
