Rhys please don't think I am having s dig at anyone on here, this is just my take on the situation.
If they aren't selling at the dealers for what they are asking then where are they going because they are going somewhere, they have to be, somebody is buying them, if the dealers were offloading them to independents and they in turn were advertising the cars at a price that people thought was closer to there true value then we would see them and be talking about them on here.
I think the dealers are in the enviable position of being able to add their £5k profit and sit on the car, if it doesn't sell they move it to another part of the country and see what happens, I completely agree it is a strange situation, private buyers cant shift them when they are £3-£5k below the dealer price but the dealers don't appear to be able to shift them either.
There we are, I have droned on for ages and still not arrived at the answer...............................
