Simon, relax you are being paranoid, I wasnt attempting to say you were involved in a scandal by lieing to webuyanycar, in fact I would be genuinely indifferent if you not only lied on a form, but also posted them a turd in the mail as well, makes no difference to me.
Surely for an insurance valuation though you would be better looking at cars for sale, than the rate they offer to buy at due to the inherently lower value that way round?
