Sure, but he has put up a good set of photos, between the 3 Ns and the Z I would say 2 are EM, one probably P4, and the third does not have a good enough pic of the wheels and chassis to make a call.Good bit is, the doubt may keep the price down, so if you have a bit to invest, buy measure, advertise properly and you should profit, mind you they are already going past my budget.
