Well, that really sucks, because I am assuming that you paid in the range of $450 for that. If he is so convinced that it is a C3, he should have no problem refunding your money and selling to someone else as there is such a high demand for C3s.

PM Valkryderguy, or FP and see if they can assist you in any way to get this resolved. Good luck, and sorry that you got duped.
