i dont know if he can help with the reselling side of things, but you can just remove it from your car find out what the buyers car spec is and tell them that you are buying a new Ford Focus and you want to reset the bluefin it will work with my new car.

It costs £120 INC VAT and DEL, so the Bluefin resale value is would say is no more then £100.
