Re: 2009 E350 Quigley passenger van
I agree. They are probably CR Lawrence windows. Not necessarily a bad thing.
As far as no back corner windows.... It works on a 12 pax van. But I've sat in row-5 of an OBS Ford 15 pax, which never had those windows. It made me immediately appreciate them.
It looks the the original buyer probably order the van as a cargo van and added seats, although it could have been an SVO order (especially seeing the factory upper seatbelt points), and Ford pretty much does whatever you want as long as you order 5 at time.
