Ok as requested I have spoken to Justmatz and they have advised the following if anyone is interested
They can supply a Euro style number plate surround like koen's but without the colour border but with any logo the forum would like.
I suggested things like civinfo.com or honda civic
but this would need to be decided if enough interest is shown
The cost would be £22 per pair plus £4.80 delivery with a minimum order of 30 pairs - or 60 plates surrounds if you only want front or rear
They would require the order to go in for everyone at the same time and payment in advance. Names and delivery addresses would be required on a spreadsheet for them to fulfil the order
Well that's the info I have got so I'll wait and see if there is any interest on the forum.
