Bugeye WRX Rear Seat
 

I have the cushion out of a Bugeye Sedan and the rear back rest out of a Bugeye Hatch if you know what I mean. The back rest does not come with headrests.
ie the bit your bum sits on is out of a sedan and the bit your back rests upon is out of a hatch.
$40 each bit and both in very good condition.
