Thus far, price is 11800 for 6 cars round trip. This is in completely enclosed transport. Obviously less for uncovered transport. The driver actually would stay in Phoenix awaiting pickup. Pickup would be in Chicago and delivery to the Hotel. Deliver either on 10/6 or 10/7 and pickup on 10/11 or 10/12 if people want to track their cars. The return date is variable since the driver is staying in Phoenix. It would be marginally less expensive to come home earlier. I will keep looking.
If interested parties would consider uncovered transport, let me know.
By the way, transport via train is around $7500 for up to 15 cars
This would be from terminal to terminal. Chime in if anyone as prior experience transporting by train.
