I have come across a single Mk6 Transit passenger seat with arm rest on the correct side. This will come complete with the base and plastic trims etc.
There are no rips or scuffs, there is a small stain in the centre of the seat which I have not tried to clean off, however I reckon if you use some sort of magic formula from the Good Housekeeping Institute it'll come off somehow. This is all represented in the photos. The plastic trim by the handles has been glued together before but seems fine.
Apologies for wrong orientation photos.
I have seen them between £150 and £200 on Ebay in varying conditions (including rips and whatnot), so I think asking for £130 is reasonable.
Please drop me a message if interested
