I've never seen one of those go for £6000. One was in auction last month and sold for £3000, which is the highest I have seen one go for. In the last 10 years I've seen about 10 of them sold and the average price is around £800 for unboxed and £1500 for a boxed one. For them to command a high price they have to be in exceptional condition.

They ones on Ebay are reproductions as are the boxes.
And by the looks of it from the pictures the OPs one is also a repro, the box definitely is as the wear is very clean. The decal colours on the model look wrong, the grille has poor definition and the silver looks hand painted and not sprayed as per the originals.
