There will be a few that slip under the net.
Every car I sell, I now put on flea bay for 1p, no reserve.
Its nail biting, half an hour before, you are looking at half the going rate. Touch wood, to date, I have always had a fair price.
I could get more, but doing it this way is a certain sale. In the past, I have had cars on auto trader for months. By the time that you have got that last pound, you would have been far better off selling it quicker for less.
