A car is only worth what you are prepared to pay for it, if the asking price is say £4,555.00p and you are happy then thats fine, I see two virtually similiar cars for sale first is £3,750.00p the other £4,125.00p, which is the better car ?, what are they worth ?, its your money and a guideline is what you seek, clubs alsways value a car more than the traders. Note do allow for anything the car needs doing to it as well, thats important.
