We were also shocked when we went to pick up the T-150 Wagon from the dealer and were told we could not take if off the lot because the dealer called our current company, 21st Century, and they refused to insure the van...even with the vin showing it is a passenger wagon.
We ended up getting coverage through Progressive, but the cost was tw3ice what I was paying on a 2013 GMC Crew Cab valued at 47K when new! Then when we received the declaration of coverage pages it was listed as a Transit Connect although they had the correct vin. After our nice independent agent contacted Progressive we now have the proper listing on the dec pages along with the correct vin and a bill that is almost exactly twice of what we were paying.
Wish I would have known ahead of time, but the dealer, no fault of theirs had only sold cargo vans. We are going to ask for quotes from every company we can find to see what we can do.
