Have these domains been branded into a great site with HUGE amounts of traffic? No, they haven't which is why I'm commenting on the value of the domains on their own, if we appraised domains on what they 'could' be worth if turned into a successful site then every domain could be appraised at some crazy amount!
They have no generic value and very little brandability..........who wants to associate their site with two car wrecks being welded together
