They are "Sakura" wembley checked design car seats, perfect match for it!
Got them from ebay but they appear to have disappeared from there (Actually I just found a set when I searched 'checked car seat'), currently on Amazon for 30 smackers as Sakura Jacquard seat covers (I need to get some new ones myself at some point.)
As for the car it seemed to be a rare colour indeed, overall condition okay however there are dents and blemishes everywhere including a badly filled hole on the tailgate from a previous owner and a nasty gouge done by my mother when trying to park it in a garage lol.
