Sorry to go against some comments on here, but its easy to sell the right car, at the right price. Mine went in under 36 hours this week, several buyers were bidding on it. It made good money, you just have to have a good spec, and bullet proof history to get a decent price.
Prices are still in freefall, and will until the nearly new market of cars starts to dry up, that will not happen for some months yet, as all manufacturers were/are still pumping out cars with no buyers for, only now are they starting the shutdowns. They then punt them out through the franchised networks, at low prices, and that further depresses used residuals.
So choices are simple, if you are only selling becuase you think you car has dropped shedloads, keep it, its relative.
If you are unlucky enough to be in a position where you cannot meet your finance payments or other monetary issues, then you will get raped, in relation to what you think your car is worth.
If you are selling to trade up, then great opportunities exist to pick up some top motors, nearly new at low prices, but no matter how cheap they seem, they will depreicate too.
When you but mass produced tin boxes, as we all do, then there are very few cars, that hold any money.
