Hello Mate,
I was needing to take some pics of my seats for a similar reason so here they are -
You may have to end up with a ED30/GTi hybrid though as you will need more of the Plaid/Tartan to duplicate the ED30 interior. The MK5 Plaid is an absolute pig to find and if you do you will pay outrageous price per meter. If your trimmer can get hold of any please let me know!!!
Any how here come the pics.........
Front Drivers seat full pic - both back and base has full length plaid/tartan

Front Drivers Base - Red stitching is the inner stitching

Front Drivers Base - Leather on Base ends

Front Drivers Back - Red stitching is the inner stitching

Front Drivers Headrest

Front Drivers Airbag thingy

Front Drivers rear of seat

The Passenger seat is the same as far as stitching etc.
Passenger Rear Back - Red stitching inner stitches - on headrest red stitching is outer stitches

Passenger Rear Base - Red Stitching inner stitches

Passenger Rear Base - Base side is leather

Door cards are normal stitching as is the arm rest. The gear stick and handbrake have red stitching though. With the door car where you have cloth the leather GTi/ED30 has leather.
Hope this helps?
