Yeah, it is 18V trim.
Also has full length hood lining, GTS dash, interior light buttons in door jams .
I can also see remnants of the sandman stripes on one side of the van.
Not sure about the seats, they appear to be the correct seats with slate grey vinyl around the back and bottom of seats but have a burgundy velour top and back. Stitching all looks original but I'm guessing they've been re trimmed.
