If I owned the car and I was asking how much I thought it was worth than fair enough. But I don't, so therefore could not accept anyones offer?! I was only after some information not just on this car, but the cars in general.
Instead of suspecting something to be something it is not, may be next time wait until such a post has been made and then take the appropriate action, rather than jumping to conclusions. As the rules are there for all to see, so if I had have turned this in to a for sale thread then it would have been my own fault if it had been deleted without warning.
