Here I have both front seats and the rear seat removed from my 2008 A3. They are Soul Black cloth seats. The fron seats have the airbags which are fine and the driver seat has the storage draw under it. There are some slight water marks on the drivers seat from when we had snow earlier in the year but they would probably steam clean out. Im not looking for a stupid amount for them, £100 for the lot but you would need to collect them or arrange for a courier yourself.
There located in the CF35 area.
Sorry about the image quality, I used the camera on my iPhone.
Thnks for looking.
