Hi there, I personally think that it is a good price. I know you have spent a shed load on it and it always looked spot on at shows.
BUT>
It is a C reg escort. From what i have seen the ones that fench MEGA money ( which i would class 6k+ as) are low milage/mint but also STANDARD. yours is far from standard and not really do able to put back.
As i said no disrespect, nice car, Just think it is a good price. Just hope for your sake that the bloke is not a messer.
good luck with the Pulsar.
