[Considered1]

The value of a car is what someone is prepared to pay for it.
Unfortunately if the dealer is offering you X for it then he's going to sell it for X+20% min in our case.

I understand that the dealer is taking the risk most of the time, needing to fix it up, put a warranty on it etc. But in my case it is mint, with a warranty and 2 years free servicing so I would rather someone came direct and split the 6K or whatever they get out of bed for these days.
